Hi,
Proton drive always list all the changes before syncing files. The problem with this configuration is that if you need 2 or 3 files just right now, you won't get them. If the amount of files in the scan is important it can take a looooot of time (once i've had 35 minutes!!) before you get your files wich makes Proton Drive a pain in the a**. It would be nice to have an option in the right click menu along with "view offline", "view online", "refresh" that would be "instant download" and that would come first when relaunching proton drive, this way you could get the files you need qucikly and then sync in the background all the rest after that...
