(Gajim was gnomed since June actually, Void Linux repos didn’t update to the new iteraction until a few days ago though so I wasn’t aware.)
Gajim was the best XMPP client for desktops, with a nice UI and all the features I’d ever need in a messenger (YMMV).
So of course it should have been turned upside-down with a UI redesign that removes compatibility with GTK3 themes while also looking extremely out of place on my system. Modern GUI design suck SO MUCH.
Hope it works well for ya! Also should mention that if you want to screenshare an application’s audio, you have to be using a Chromium based browser currently, due to it still being pretty new.
