Yeah, so I have my own client... I'm planning to implement a component for simple filesharing (really just a kind for magnet links, but the current file-metadata NIP isn't ideal)... Would you be interested in taking a look? Say, second half of next week or the week after that? Word of warning: it's ugly, built in Godot, and communicates with a python script using plain text files. Really it's a mess but it works.
