This request is mainly cosmetic but I think it would make a lot of sense. Actually I’m a little surprised this isn’t standard behavior with the tight integration of the two services.
People have their avatars in RC but when a Jitsi meet room is started (or joined) from within RC we are stuck with the random avatars that Jitsi serves us. It would be nice to have the RC avatars handed over to Jitsi. For guests the random avatars are fine.
