While there are many similar tickets regarding this topic, i just wanted to add my specific request, ignoring the often posed usefulness question of treating the photos section completely separate to the overall file section.

With this current structure in place, I would love to have the option to mark whole folders in "files", making them visible in the Photos Album section. In my case, I store my Photo backups in Proton Drive, organized by a certain folder structure. (mostly organized by year/location/event) While i don't want to clutter my photo album section with all these photos stored in Files, it would be great to make certain event folders visible there. (especially since file folders can't be viewed in the same way photo albums can, an option which, while not ideal, would at least ease my pain in regard to viewing photos in my proton drive file section)
