If you are interested in Pidgin, the lead developer has a Twitch stream (rw_grim). He is always open to ideas, and onboarding new contributors. There is a new version of Pidgin being written that significantly improves the user, and developer, experience. If you check out the stream, you could get some swag too (I have some Pidgin stickers). That said, I am also interested in Dino, and supporting other projects. It's unfortunate that chat has become more proprietary, instead of more open.
