Trying to change from Onedrive, but it's on-demand file download is too powerful. Apps & Games being able to call for and wait for a Onedrive download automatically should be a feature of Proton Drive.

Also ability to have all Windows PCs synced under one location in Proton drive. so they all have the same files available. Proton Drive having PCs have there own individual folders was a big let down when I was changing over.
