What could be improved in Proton so that more people would buy subscriptions?
Proton pay - I use GrapheneOS, and I'm missing software that can replace Gpay, that I can trust with my data, and that I want to use with NFC.
Proton notes - Right now, I'm using Notesnook. Obsidian seems too cluttered for me, while Notesnook looks minimalistic. I use to-do lists and tables, because it's convenient for me to have everything in one app, but maybe in the future I'll start making tables in Proton Sheets.
Proton to-do-list -In Notesnook, I have tables, notes, to-do lists, all of which are missing from the Proton app. At least the to-do list and notes are there, and you can switch to tables in Proton Sheets, but I haven't seen the need for that yet.
Proton forms
Proton RSS Reader - I use the minimalist BazQux Reader, but I would like a confidential one from Proton.
More support for Linux, because there are more people in Linux who care about security and privacy.
I believe that these innovations will make Proton much more popular and many people may switch to Proton, while others will purchase more expensive subscriptions.
