There’s a button to “sort” folders in the settings which sorts the currently existing folders alphabetically. Then when you create a new folder it gets put at the bottom. Can we just have them sort alphabetically automatically?
Also when you click sort, it only sorts the top-level folders. The subfolders don’t get sorted at all.
This is the kind of rough-around-the-edges stuff that Proton really needs to sort out before adding more and more services.
Numbering the folders isn’t dynamic though. If you add a folder later you might need to rename others, which is annoying in itself but then would break any filters applied to them too. I’d rather just organize them as I want manually. It’s not hard to drag and drop them.
