Screenshare window optimisation

I've been using screenshare when playing with friends for a long time now, and discord is TERRIBLE at optimising the space of the monitor when I'm looking at several screenshares.. (at least we can finally hide our own screenshare thank god). Here are some examples about what I mean, I find whenever I have 2-3 screenshares open, I'm better off using my 1920x1200 monitor in portrait instead of the one in landscape because of how it puts the screenshares on my screen.

Is there a plugin that optimises the space more, gets rid of grey borders, or lets me split the windows into individual ones? Especially when I'm playing with 2 people that have 21:9 monitors, it's bizzare how discord would rather put two 21:9 monitors side by side instead of above and below..
