The photos viewer is nice but it would still be good to view the photos as normal files as part of the file system and makes them syncable to computers.

This would allow the user to manipulate the photos once they're in Proton Drive and limited to the UI. Once you upload them, it's almost like they're inaccessible to anything but viewing.

It would also allow the user to organise/rename/edit the photos on their local computer rather than them being "hidden" away and only accessible in the UI. Although there are albums for organisation, folder based organisation would also be possible which would not show in the Photos view.

The photos view would stay as-is, perhaps allowing a customisable selection of folders being available to select for the Photos view to search through for photos.
