That's right, FAQ and other help needs much more attention :)
I don't have a github for this, don't have plan to open source it atm.
The nostr search features are gonna expand, I will allow replying right on my site if you have Alby, and will open up some good third-party web client when it comes. For now I just manually copied user IDs and used them in other clients to find people and reply.
I didn't use mastodon and matrix when I wrote the 'about' page, gonna go add nostr now :)
Thanks a lot for a huge amount of feedback!
