I wish I could! I'm not preaching anything here, my own personal projects look nothing better than this, as I'm a developer, not a designer.

And even if I was a UI/UX person, I think this is a deeper problem than a patch could solve.

Hello, do you know how or who should I approach in order to offer my studio's professional services (for free of course) for tackling this UI problem? I want to commit to this, but with some kind of planning, just blindly sending PR's seems like its not gonna be throwing hours go the void.

I think most companies, especially now, want a turn-key solution with support in case of an issue. The fact that Zoom, Teams, GoToMeeting, WebEx and Google Meet are closed sourced is a non issue for most organizations. They want something that works right now.
