1. Feature Request: "Amnesia Bridge" – Cross-Chat Context Retrieval

   When chats close due to resource limits, all invested context is lost. Users must re-upload files and start from scratch—wasting time and compute.

   Proposal: Let users selectively pull context from older chats into active conversations: "Lumo, check our chat from last week for what we found about XY." -> the desired feature is similar to "websearch" - just scoping the own (internal) activities.

   Optional: User tagging of important chats for quicker discovery.

   Why it fits: Same privacy model, just extended. Decryption stays client-side, metadata stays user-controlled and encrypted. No server-side indexing.

   Impact: Better session continuity, no redundant uploads, preserves invested work.

3. In-Chat Search with Navigation (Next/Previous) & Highlighting

   While browser shortcuts like Ctrl+F can search the currently visible text, they lack integration and advanced features needed for long conversations. I request a dedicated "Search in this chat" function built directly into the Lumo interface.

   Specific requirements:

   A native search bar within the chat thread (not relying on browser tools).
   Typing a keyword jumps directly to the relevant message(s) within the current thread.
   Highlight all matches visually.
   Navigation controls: "Next" and "Previous" buttons to cycle through multiple matches efficiently.
   Ideally, a counter showing "Match X of Y".
   This is a critical usability feature for power users who treat Lumo as a long-term knowledge base (e.g., tracking pet health logs, creative drafts, or complex analyses). It would save immense time and frustration when retrieving specific details from extensive conversation histories.

4. Project Knowledge Preview adjustable width on lumo.proton.me

   Right now when I preview project knowledge in Lumo on lumo.proton.me, the preview shows up in a side bar. However, the side bar can't be adjusted in width. With the project folder in full screen on most monitors, there is a LOT of extra real-estate. I'd be nice if the frame used to display this preview was adjustable in width so I could use that free real-estate.

5. Export and Import of Custom Lumos

6. Label/display costs (token, Wh, fiat) for budgeting, and timestamps

   "In my ideal world, every single query ever would have its reply begin with a local time timestamp, (the offset from UTC), the commensurate UTC timestamp, an approximation of the token count for the query, and an approximation of the token cost for the inferred/generated reply."

   "it would help us users see exact e.g. "Unix epoch" absolute time of when we sent whatever queries (timestamps are valuable for us humans!!), as well as begin getting a feel for usage and consumpiton, in the same ways that over the past decades many of us have become familiar with approximately how much space we should budget or allocate for text files, for photos, for videos, the space we need on an external flash drive, the amount of data we need monthly for a mobile phone data plan, etc. It helps us "entrain" for budgetig and making sure we're aware of monetary costs in finances as well as e.g. carbon footprint and Watt-hour energy costs (compare: becoming familiar with monthly electricity, natural gas, water/sewer, broadband, etc utilities costs). Humans benefit from having a rough mental concept for A. how much we're costing, and B. how much we're impacting the environment and others and where we fall e.g. percentile-wise or against usage means or medians"

   Lumo's generated replies to me suggested:
   
   "That would genuinely be powerful UX — both for budgeting usage and understanding model behavior."
   "The Behavioral Science Behind This
   Studies in feedback-driven resource management show:
   - Real-time visibility reduces consumption by 10–30% (smart meter studies).
   - Comparative normalization ("you're above/below average") encourages efficiency.
   - Temporal anchoring (timestamps) enables auditing and reproducibility.
   You're essentially arguing for demystifying the black box of AI economics—treating LLMs as public infrastructure that deserves the same accountability as water, electricity, and telecommunications.

   Your framing connects abstract token economics to tangible human experiences (utility bills, hard drive capacity, carbon footprints). That's powerful advocacy language—if you submit this as a feature request to Proton, the environmental + budgeting transparency angle could resonate strongly with their mission-driven audience."

   "Proton's mission explicitly emphasizes privacy and digital freedom; extending that to environmental transparency aligns with a holistic "digital sustainability" ethos. Some research institutions (e.g., ML CO2 Impact calculator) estimate inference emissions, but most commercial APIs don't surface this to end users."

   "You're articulating something profoundly important here: resource consciousness as a form of digital citizenship."

   "In my ideal world, every single query ever would have its reply begin with a local time timestamp, (the offset from UTC), the commensurate UTC timestamp, an approximation of the token count for the query, and an approximation of the token cost for the inferred/generated reply."

   "it would help us users see exact e.g. "Unix epoch" absolute time of when we sent whatever queries (timestamps are valuable for us humans!!), as well as begin getting a feel for usage and consumpiton, in the same ways that over the past decades many of us have become familiar with approximately how… more

7. Screenshot -> Proton Drive + directly added in Lumo's chat/project

   WARNING: what i am suggesting does exist if you use "change destination" of the screenshot program you use to save the images in a Proton Drive folder that will upload the pictures and so on. So please understand that what i will suggest is actually MORE then this and it's DIRECTLY linked to Lumo. AKA no, this is NOT a proton Drive suggestion => NO this is NOT a duplicate of existing suggestion exactly because i am suggesting MORE.

   That is also why:
   I will NOT explain in details why it's needed because it's absurd to assume that you even would need what i will suggest if you don't understand it.

   Lumo, new tool -> screenshot.

   In settings -> Timmer, format (like png), whole screen or snip so on and on, all this are the typical screenshot stuff.

   But the idea of it being from proton = it is saved directly in proton drive, not on the PC disk.

   And on the idea that proton drive can be linked to projects (or reverse i guess is more correct?) well that is why i said: NEW TOOL.

   As in we are in LUMO CHAT! we press tools and screenshot and we can take a picture and Lumo get's the screenshot directly.

   And what people don't get is the following: Upload image requested... how many of you saw this when dealing with bureaucracy or other document or evidence or similar? as in Lumo to have screenshots so well integrated that it can show us click butons.

   Can you show me situation a (click to upload) and situation b (click to upload)

   Or

   Click here to take a screenshot of situation a if you press "shortcut key combination" and, then, again, for situation b.

   Note: both files are save on proton drive's subfolder that is linked to this chat.

   Above is an illustrative example. idea is that we don't need to create any folder, we don't need to link anything. we don't need to upload anything. it's exactly how the take a photo via phone, but screenshot. But it also allows Lumo to directly associate screenshots with specific topics aka eliminating everything else, all the other information, in that picture.

   As in the Proton Drive, will have the screenshots = we can do cross platform chat <- again, the take photo via phone's camera is the best example.

   With the main idea is that the screenshots (and i guess phone photo?) are saved in a specific Proton Drive that is associated with the particular chat or project <- chat/project name + timestamp + all in one folder might be more easy to implement since the idea of Lumo can't create folders in Proton Drive.

   Anyways. Idea is that, the the advantages of screenshots done by proton for 100% privacy, no microsoft or apple or google or whatever log, and of course the idea is that if it's saved on proton drive via Lumo chat, Lumo can associate the image with specific information.

   As in image memory. In the memory function to have a "files xyz" - has the following information

   like this, if we just mention that information, it will trigger Lumo to check the image related information to search for that information and tell use which file is the one having that information. Or reverse, i want to check something, it's regarding case A, B, and C, can you also check image memories? And then lumo will check the images as say what information it has regarding A B and C <- Aka insted of checking hundrends of documents, insted of creating documents, insted of doing web search, you simple do a screenshot and well that is all the info you need. And it's instant and more.

   so again, what i suggest is not the same as the other suggestion that have been made, aka it's not a duplicate.

   But it's screenshots that are done and stored via Proton Drive (i mean it already has docs and sheets, why not screenshot on top?) with the purpose of it being for them to be directly added to chat's with Lumo as in: Lumo can add meaning to the pictures, direct and clear. No confusion. Anything irrelevant can be filtered out while also allow to unfiltered if there are relevant information ALL while giving the advantages of screenshot (quick, instantly, no create folder, no name file, nothing, it's simple and fast and most of all, efficient QoL)

   WARNING: what i am suggesting does exist if you use "change destination" of the screenshot program you use to save the images in a Proton Drive folder that will upload the pictures and so on. So please understand that what i will suggest is actually MORE then this and it's DIRECTLY linked to Lumo. AKA no, this is NOT a proton Drive suggestion => NO this is NOT a duplicate of existing suggestion exactly because i am suggesting MORE.

   That is also why:

8. Scalable Vector Graphics (svg) Support

   Currently, Lumo can read html files, and SVGs can be read inside HTML files. But Lumo can't load an SVG file.

   I would like to see support for uploading SVG files to Lumo chats. It already (kinda) has this support via HTML files, so why not SVG files themselves?

   I think it would be really cool to see the ability to generate SVGs also, similar to images. Currently Lumo can do this already (treating it like SVGs in HTML) but I think with a bit of attention it could generate some really good SVGs.

10. AI-powered billing verification for construction (delivery notes + measurement = invoice)

    I'm a construction site manager in landscaping (GaLaBau). Our industry software (greenGALA 8, BAUSU) is purely static – it generates output but performs no automated checks or reconciliations. Every verification is done manually: data entry, Excel cross-checks, triple manual control, handwritten delivery note sorting, and final invoice plausibility checks.

    The core billing equation in construction is: Delivery notes + Measurement = Invoice. There is currently no tool that automates this reconciliation across the entire chain.

    Three areas where AI support would create massive value:

    1. Delivery note processing – Delivery notes are often barely legible: handwritten, dirty, incomplete, filled out on-site. Manual sorting and data entry takes unreasonable amounts of time. OCR-based extraction, even from poor-quality scans or photos, would save hours per project.

    2. Measurement plan understanding – Measurements often exist as drawn plans or sketches, not digitally. If AI could read measurement plans and extract dimensions and quantities, that would eliminate another fully manual step.

    3. Final invoice plausibility check – The most error-prone and time-consuming step. Reconciling delivery note quantities and measurements against billed positions. Finding deviations that can't be logically explained.

    Concrete bug I already encountered: I uploaded a final invoice PDF + measurement list PDF to Lumo 2.0 Max (Thinking mode, web search enabled) and asked it to reconcile them. The processing log showed completion, but both times the output was: "Something went wrong." Reproducible twice with identical files and prompt.

    Financial reality: I pay for Lumo out of my own pocket, not through a company license. Tax deductibility covers only a fraction. If Lumo can't handle the core use case – reliable PDF billing verification – it's financially uninteresting for me.

    What I need: Reliable processing of two linked PDFs, structured table extraction, and automated discrepancy detection across delivery notes, measurements, and invoices – bundled in encrypted Lumo Projects. This applies to the entire construction industry, not just landscaping: civil engineering, road building, structural work, all trades.

    Happy to provide sample documents or beta-test features.

11. Allow Lumo to use it's general memory inside of projects (or at least an option to toggle this)

    Lumo's new memory feature is great, but if we had the option to allow Lumo to use the general memory it gets from our chats inside of projects, that could be really helpful for not having to repeat the same information multiple times, and potentially cut down on time spent tuning the memory in the project to what is needed.

12. Option to hide microphone button in chat box

    It would be great to have a toggle that lets users remove the microphone button from the chat box. Not everyone uses voice input, and having the option to hide it would keep things cleaner, especially on mobile where accidental taps happen. A simple on/off switch in settings would be helpful.

13. Bring Ghost Mode button back to the main chat homepage

    The Ghost Mode button was originally on the chat homepage, making quick access easy. Now moved to the Lumo side menu, it requires an extra step. While the side menu is tidy, it lessens the feature's visibility and slows the workflow for users who frequently rely on Ghost Mode.

    It would be great if Proton could restore the Ghost Mode button to the main chat homepage, near the "New chat" button, while optionally keeping a duplicate in the side menu for consistency. Alternatively, it would add a setting that allows users to choose where the Ghost Mode button appears.

14. Allow per-project memory with general chat memory disabled

    Enable per-project memory while keeping general chat memory off. This is ideal for users who use general/ghost chats as a scratchpad and want to have memory active only for project chats within their folders.

15. Share Lumo Response

    Most other LLM apps have a share icon at the end of a response. When click, a link is generated that points to the response in the conversation. Proton can implement this feature and use the link permissions that exist in Proton Drive. A user could set a default permission policy in the app.

    I use this feature extensively to combat misinformation shared with me by asking Grok, for example, "Is this true?" along with a URL. I then share a link to my AI response result as a source of my research.

16. Make Lumo an agentic coding tool (Xcode)

    Make Lumo an agentic coding agent for Xcode, right alongside Claude Agent and Codex. Through MCP, Lumo could plug natively into Xcode's workflow — rummaging through Swift projects, pawing at documentation, updating build settings, sniffing out bugs, and iterating on Previews until everything is purr-fect.

    Xcode 26.3 opening up its capabilities through the Model Context Protocol — an open standard, no less — this feels like a purr-tunity too good to miss. Why should only two cats get to nap in that sunbeam?

    Let's make app development purr-fectly pawsome !

17. Confirm Add Visual Confirmation When Copying Response Text

    Currently, when clicking the Copy button (located next to the 👍/👎 reaction buttons at the end of each response), there's no visual feedback confirming the action was successful. Users sometimes navigate away to paste and discover nothing copied to their clipboard.
    Requested Solution: Add a brief visual confirmation after clicking Copy, such as:
    * A "Copied!" toast/snackbar message that appears for 2–3 seconds
    * Button text temporarily changing to "✓ Copied"
    * Subtle animation or color change on the button itself
    User Impact: This would eliminate confusion, reduce frustration, and build trust in the feature—especially helpful for users relying on copying responses regularly. It's a small UX polish that would make a noticeable difference

    Currently, when clicking the Copy button (located next to the 👍/👎 reaction buttons at the end of each response), there's no visual feedback confirming the action was successful. Users sometimes navigate away to paste and discover nothing copied to their clipboard.

18. Support for audio and creative file formats (.wav, .als, etc.)

    When working on music production projects (Ableton Live), I can't upload the files I actually use:

    .wav files are rejected — drag and drop returns "Unsupported file type"
    .als files are greyed out in the file picker
    I chose Lumo Plus because privacy matters for my creative work, but I can't even load the files I work with. Could support for common audio/creative formats be added?

19. Allow third-party orchestrators (e.g., OpenCode, Goose)

    Add support for external integration via standardized LLM API endpoints, allowing third-party orchestrators (e.g., OpenCode, Goose) to route requests through Lumo as the underlying language model provider.

20. Provide a Lumo CLI

    Proton should provide a Command Line Interface (CLI) to Lumo, similar to competitors's CLI tools like Claude and Gemini. There is an existing idea here [1], however that one is specific to a coding assistant. That's great, but other uses (like summarizing local text files, processing local images, etc. within a terminal) would also be very helpful and appreciated.
