1. Automatically detect and prefill event time from text entered in the description field

   When a calendar event description starts with a time (e.g., '17:00' or '5 PM'), automatically detect it with regex and prefill the event’s time fields—simple to implement, high user value, inspired by Google Calendar. (or let me know and I will implement it for you <3)

2. S/MIME signature validation support for e-mail clients via Proton Bridge

   Please add support, that an e-mail client connected via Proton Bridge is able to validate S/MIME signature.

   Reason: Banks, delivery services, public authorities, etc. use S/MIME signed e-mails to prove that an e-mail is genuine. This helps fighting fraud, fishing and other criminal activites.

   Context: Currently, S/MIME signature cannot be validate in Proton Mail. A validation with an e-mail client connected via Proton Bridge cannot validate an S/MIME signature because Proton modifies e-mail headers that are essential for a successful S/MIME signature validation.

   The posted idea "S/Mime Support" at https://protonmail.uservoice.com/forums/284483-proton-mail-calendar/suggestions/16574134-s-mime-support requests for much more: a full S/MIME implementation.Although full S/MIME support would be great, in my opinion, the most important part is to be able to validate S/MIME signatures.

3. Email all participants

   Like in Outlook, add an "Email all participants" Button to events.

   Should open a Mail, like a reply all to the event. This is helpful for where I want to tell others, e.g.:
   * "Sorry, I will be late"
   * "Here are more details about the event"

4. Edit/add participants on existing events

   I received a booking email and Proton offered me to add the event to my calendar. Once it was created, I wanted to add participants, which seems to be not possible. It would be great to be able to edit the participants list on existing events, without having to create another one.

5. Provide a Way to Disable HTML in Emails

   Html is very present in emails from CRM software but is rarely ever present in emails sent from friends and relatives. It is unnecessary, wastes space, and presents some vulnerabilities and tracking potential. Scammers can use html to obfuscate urls for phishing attacks, and companies can use images to track opens. Can Proton add a way to either strip html from emails before it reaches my inbox, or disable the rendering of the html once it is in my inbox, or both? Or at least disable the rendering of links specifically, so that they can no longer be obfuscated? Outlook has a way to do this, and it works great, but I'd like to be able to check emails in my browser as well, without having html render there.

8. A bridge for the Proton calendar

   I would like to have a bridge, as realised with the Proton email, with which the calendar entries in the Proton calendar are mirrored in the standard calendar on the Mac or iPhone. Then they would also be displayed automatically on the Apple Watch.

10. Advanced PGP Key Management for Proton Mail Users

    Description

    Currently, Proton Mail allows users to manually add PGP public keys to external addresses only.
    
    This creates several limitations for users with more complex encryption setups or personal key hierarchies.

    ---

    Problem 1: Limited Manual Control

    Users cannot manually specify whether an email should be:

    • Signed only
      
    • Encrypted only
      
    • Signed and encrypted

    Instead, Proton Mail enforces a fixed default behavior per contact.
    
    If a user wishes to change how messages are sent, they must manually adjust the contact’s encryption settings each time.
    
    This slows down workflows and complicates secure communication.

    ---

    Problem 2: External Keys for Proton Addresses

    Some Proton users maintain their own personal PGP key pairs associated with their Proton-hosted email addresses (for example, to preserve local control or maintain a separate trust model).

    However, when receiving messages from other Proton Mail users, Proton’s system automatically forces the use of the Proton-managed encryption keys, preventing users from:

    • Assigning their external public key to that same Proton address, or
      
    • Choosing an alternative key manually for encryption/signing.

    This limitation breaks compatibility with privacy-focused setups or air-gapped key workflows.

    ---

    Problem 3: Security Tradeoff

    The only workaround — uploading the external private key to Proton — undermines the purpose of maintaining an offline or self-controlled key.
    
    Even if Proton’s storage is zero-access, this still requires trusting Proton’s infrastructure with a key that ideally should never leave local custody.

    ---

    Suggested Enhancements

    1. Manual Key Override
       
       Allow users to override key selection on a per-message basis, including:

       • “Sign only”
       • “Encrypt only”
       • “Sign and encrypt”
       • “Send plaintext”

    2. Custom Key Mapping for Proton Addresses
       
       Enable assigning an external public key to a Proton-hosted address, even when interacting with another Proton user.

    3. Per-Message Key Selection UI
       
       Add an “Advanced” or “PGP Options” dropdown when composing a message to select signing/encryption behavior or which key to use (similar to Thunderbird or GPGMail).

    ---

    Rationale

    These improvements would benefit advanced users who manage their own key infrastructure or use Proton as part of a broader privacy toolchain.
    
    They enhance flexibility and control without compromising usability or Proton’s secure defaults for non-technical users.

    Description

    Currently, Proton Mail allows users to manually add PGP public keys to external addresses only.
    
    This creates several limitations for users with more complex encryption setups or personal key hierarchies.

    ---

    Problem 1: Limited Manual Control

    Users cannot manually specify whether an email should be:

    • Signed only
      
    • Encrypted only
      
    • Signed and encrypted

    Instead, Proton Mail enforces a fixed default behavior per contact.
    
    If a user wishes to change how messages are sent, they must manually adjust the contact’s encryption settings each time.
    
    This slows down workflows and complicates secure communication.

12. email sweep

    Microsoft's Outlook email app has a feature called "Sweep," which allows one to highlight an email, and then take action on and set up a rule for all emails from that sender.

    Options include:

    Move all messages from the Inbox folder
    Move all messages from the Inbox folder and any future messages
    Always keep the latest message and move the rest from the inbox folder
    Always move messages older than ten days from the inbox folder

    The default destination is "Deleted Items." Other options include:
    Junk Email
    Inbox
    Archive
    or any other folder the user chooses or creates.

    It is very helpful for keeping one's inbox tidy, and could possibly ease the storage requirements on the server. It greatly simplifies the task of deleting an entire class of emails.

    While I appreciate Proton not wanting to overcomplicate its products, it is possible that the overhead implementing it would entail might be obviated by the savings in storage.

13. Allow customisation of Proton Calendar display (font etc) and other things - my top 5!

    I think it's new, I cannot find any customisation of fonts for calendar app on iOS...

    Having used CalenGoo for Google calendar, and now migrating away from Google, I can only strongly suggest to look at the depth of customisation that CalenGoo offers over even the native Google Calendar app.

    Highlights for me, not exhaustive:

    • customisation of font size, bold/italics etc., style, colour: important to allow more to show in the week and particular month view (my preferred view)
    • display time at the start of a scheduled meeting in month view, not just 5 or 6 letters
    • a proper search function (with indexing on device prior to encryption)
    • general display alterations/customisation (for example, why not allow display of "August 2025" at the top, not just "August", which could be any year...)
    • an easy copy/paste function for regularly recurring events where only date/time changes, not the content of the event

    This is only a list of my most liked highlights.
