Hi,
would be awesome, if the Drive have a functionalities for media playback. In my case, I'm talking about audiobooks.

Audiobooks (and music albums) have multiple files mostly. So I can listen to them, at the end of one file automaticly jump to a next file. And be able to sync the listening progress - when I stop listening in the middle of an audiofile on my PC web browser Proton drive, I can continue listening on my mobile phone or tablet in a Proton Drive app from the same position.

It can also apply for video, or better all media, files.
