I'd be happy with just being able to edit .txt documents.

Proton Drive for Business needs a way for my team to collaborate on files. As it stands, my team members cannot access any of the files that I upload. This is a major pitfall.

As the administrator, I should be able to set up specific folders for my team to be able to share. We should all be able to access these folders in our respective drive accounts to upload or remove files.

These shared folders should also still support link sharing.

We are a team of genealogists, so we would greatly benefit in being able to collaborate on folders, but we still need to share these folders with our clients.

A sync app would be very nice indeed. One thing I like about the Dropbox app on Windows is the automatic screenshot upload feature. Proton should copy that feature too :)

I was fortunate enough to be rewarded with a nice 3Tb of storage, for being a Visionary Subscriber at the time of the recent rebranding.

That being said, let me also add: I am VERY eager to find secure, privacy-conscious storage, and Proton Drive would sound like the exact best solution possible here.

So... why am I not using it?
Literally because I can't see the point in atrocious connectivity that is required or only possible via browser, alongside failed uploads (though, to Protons credit, the upload failures have definitely improved in that they are much, MUCH less frequent now. I know the teams are working!). Just in general, my biggest complaint here is that I don't really understand, from a technical perspective, how much different or how difficult it could really be to offer a setup much akin to the Proton Mail Bridge app:

Redirect all of the upload/download/link requests to localhost, essentially just a reverse proxy or perhaps more accurately, a really basic SSH tunnel can do this & would enable use of protocols like RSYNC or even BorgBackup. Those sorts of solutions seem very doable. I know the team at Proton is certainly capable too!

Here's (seriously, really, really) hoping! ... and now, I am sadly off to go purchase one of these black Friday deals from a cloud storage provider, which I will spend way too long vetting on privacy standards *sigh*

lol but really, please? <3

This so needs to happen. Web-based apps are the new trend, and Proton would be well-served to get such functionality up and running.
Personally, I don't need 'sync buttons' on my desktop, but going right to Proton Drive interface with a single click, esp. with the 'app-like' settings as with the Mail desktop shortcut the user is provided with upon configuration, would be highly desirable.

Honestly, there are already a lot of good sync clients available already. If you only made available one of the protocols already supported by rclone, you could save a lot of work on the client and Proton Drive would actually become useful.

This would be incredibly hard to develop from scratch (though it would be cool).

LibreOffice integration would be *really* nice. At the very least, prioritized native support for Open Document files would be helpful.

Another option would be integration with CryptPad. As it's federated, I think it would be realistic for Proton to make their own instance of CryptPad with Drive support. IT is already incredibly secure (as far as I am aware), and it supports Rich Text, Spreadsheets, Code/Markdown, Kanban, Slides, Whiteboard and Forms (see https://cryptpad.org/about/, try it at https://cryptpad.fr/ ). I'll probably post my own idea about integration lol

So much needed feature. Linux and Mobile please!

A secure and end-to-end encrypted notes app would be awesome cause there is no such famous app. It can convince even the most pessimistic people to put away paper and pens and get an online notebook

I would love to have a desktop app that would selectively sync files from my PC/Laptop to Proton Drive

I won't buy a subscription without desktop sync.

It was supposedly coming 2 years ago.

That's a not a good sign.

I definitely need more secure spreadsheets than google sheets. the whole set of google docs/sheets would allow me to get off google.

Being able to edit spreadsheets on mobile would be greatly appreciated

Those of you following this idea should look at the recently-published Proton Drive roadmap: https://proton.me/blog/proton-drive-roadmap

Come on guys! I know you can make this happen 👍

this along with a proton photos equivalent to google photos should be top priority. Two big milestones to achieve.

As an iPad and Windows PC user, I would like to see a full integration of the app with productivity apps (Word, Excel,PDF Expert, etc...) similar to Microsofts' OneDrive. At the moment, with only a browser interface, Proton Drive does not meet my needs.

Well, Linux client is necessary, indeed. But not all users are using GNOME as a desktop environment, although GNOME Online accounts should definitely include Proton accounts. Also KDE has its own Online Accounts inside Control Panel and Proton account support would be good addition also there. Moreover, today KDE is quite resource-efficient. E.g. empty system took ~718 MB of RAM with KDE 5 Plasma desktop with EndeavourOS.

Interested in ProtonDrive for Linux.

If resources were made available, the open-source community may be able to come up with a solution. Many here also mentioned insync collaboration as well. This could be a way to boost both of your customer bases.

Finally, in this guy's opinion, collaboration and integration with GNOME via the GNOME Online Accounts would allow you to easily support and advertise to a Privacy and Security-minded community.

Many potential customers may be self-hosting NextCloud.
