Not many options for cloud-based privacy PKM. MyMind features are great but they refuse to allow persistent collaboration (teams, family, etc). My wish list for this product would be:
- browser extension (FF and Brave)
- Lumo integration
- Image OCR / color (hex + paint chip) found
- spaces for organization and collaboration
- templated cards for popular services (see MyMind: imdb, wikipedia, spotify, reddit, etc)
- Highlights from Readwise / InoReader etc.
- youtube transcripts
- Audio to text
- knowledge graph visual showing connections between content / the ability to link content / suggestions for linked content

Our knowledge management now runs on Slab. It used to run on Samepage before it was discontinued in Europe. Having a similar solution in Proton would be great.

Key things we need:
* full text search
* instant visibility of where the article (page) lives within the knowledge base structure
* simple linking between pages through @
* instant moving between pages
* tagging
* fast editing with / commands
* easily embeddable external resources

Having this natively on Proton would integrating the material with Lumo much easier and more secure.
