Yes, file tags would make things so much better. Refer to MacOS file tags. As another user suggested, Proton Mail labels is a good way to implement tags also. Being able to have multiple tags for each file would be wonderful. This is one of the main reasons that I really can't use Proton Drive. What you've created so far is very good. Given that files are searchable from the browser interface makes Proton Drive reasonably useful, however I haven't adopted Proton Drive yet mainly because of the file tags issue.
