It would be gold to be able to watch more than one stream on one monitor via splitscreen. Perhaps up to 4. This would be a great way to keep track of several of your favorite streamers and be able to focus on the one with the most action at the time. Individual mutebuttons and being able to change the size or each videofeed is a must. Right now the only thing you can do is to stack webbrowser windows but each videofeed gets tiny. I'd like this function to operate in fullscreen mode with as little excess space as possible.
There's my suggestion. Thanks :)
