I think it would be useful to have an optional “Gaming & Entertainment” category or folder template in Proton Drive.

Users could organize game-related files such as configuration files, manuals, screenshots, save backups, emulator documentation, and other personal gaming resources in one place.

This could be particularly useful for people who maintain collections of older games and emulation-related documentation. For example, I often find it helpful to keep PS2 BIOS and emulation reference information organized alongside other gaming resources. I’ve also put together some information about PS2 BIOS and emulation here:

An optional template could include:

Game Saves
Configuration Files
Manuals & Guides
Screenshots
Emulator Files
Other Gaming Resources

It would be a useful organizational feature while still fitting Proton Drive’s focus on private cloud storage.
