Oh, good to know, so Yana is the successor of Nostrmo and I didn't even know Nostrmo existed?
Yes, nostr:npub1gp4xzpmluelsakjtayc4wtzj97fhj5kakqjvsannu00xkdlf4x8s0xdqyq used some initial code from nostrmo.
But signature verification in nostrmo is turned off because bip340 dart lib is too slow.
I had to use native android channel and use acinq lib in order to be usable.
Main dev says he has no time anymore to develop it.

other newish clients are Lume ; nostr.kiwi & zappdit (mainly for communities), though I'm sure you know about these
Micro-apps include nostatus & nosli .
There are so many tools for post admin: checking which relays have a post, checking if a post is deleted, backing up posts, copying posts from one relay to another that I lose track of them😔
