[feature request] add sorting option

It is indeed beautiful!
I was wondering if you can add file sorting option. It is currently sorted by time. Sort by filename would be handy as well.
Thanks

Start by locating the Python/Flask code that builds the file listing, since the issue does not name a file or test. Check how entries are currently sorted by time, add filename sorting as an option, and verify that the listing order changes correctly without breaking the existing behavior.
