With windows explorer and Proton Drive alikes, I am used to having contextual menu with options like:
- Always keep on this device
- Free-up space
- See online
- ...

It is partially implemented when browsing within the proton drive folder, but it missing with the other synced folders like "Desktop" or "My Documents"

PS: Along with the contextual menus, it would be nice to have information like sync status appearing in the explorer like with most Proton Drive counterparts.
