Overall feedback from a long-time user and a Discord refugee

Thanks for clarifying, promising to hear.

In regards to streams, I wasn’t talking about a popout window or fullscreen.

I’m talking about fullscreen “mode” where part of it gets occupied by chat and the video fills the rest of the screen with no other UI elements, no taskbar, no window decoration, just like you would expect from fullscreen. Like what they have on YouTube streams and in Discord calls:

Ideally the background should also be either pitch black or configurable, like in the examples above.
And preferably this indicator in the corner should not be displaying all the time:
Live indicator
