The way proton drive fractions everything into incompatible storage areas makes no sense. I just need a folder to store my files, synced across all devices. Depending on how I try to add files they go to:

• a photos bucket that isn't in "My files"
• a "My computer" section that seems to also not be in "My files" (and seems to split things out by device)
• ??? if I try to drag and drop them between two file explorer windows on the local machine
• "My files" if I open the web application and drag them in there (abandoning the Proton Drive application entirely)

Just make a folder, a simple folder. Your photo backups go there in a subfolder (OneDrive uses Camera Roll, but even allows you to specify the path), your device backups go in sub-folders if you specify that for machine specific backups. Otherwise stuff that you put in there is in there...where you put it. Simple. You don't even need a "My files" folder at all, just mount them directly in your specified path for Proton Drive.
