The Khatru docs are exciting. This is great, thanks. 

...but it revives this craving I have for a client that surfaces Relays as a first-class UX citizen. 
That is, "browse the feed of x y and z relays". "post this note to Foo relay only". Etc. 
I can imagine creating all sorts of excellent purpose-built relays, but they end up all dumped in my client's big relays bucket and I can't easily read ONE relay or make sure I'm posting notes to ONE relay. 
This basically goes for all currently good clients.  

 Is there a client out there that foregrounds relays like this?
