Wayland and audio is fixed, but only on the canary branch for the moment, this isnt lazy either, they changed the whole screenshare flow to suit linux’s permission prompts
I mean I am not sure, but in matrix you can just “reply” to a comment in a chat room and therefore create a thread? In discord you can have whole “chatrooms” be transfered to discussion only with threads. I am not sure about the terminology but it looks very different to me. Basically, you can set Discord up like a community board etc.
