I love the AOT window of the Electron app when it looses focus. Great for presenters sharing their Powerpoint for instance, which goes full screen. It is hard to believe, but most people present with one screen and can loose their connection unnoticed (quite painful).
This is also why an AOT chat would be so very helpful. In practice with big groups, chat is the way to communicate during a presentation. I saw Zoom has this feature as well… Could also be a part of the AOT video window of course. Even just displaying the chat would be great. It already has cam and mic control buttons…
