Moving other peoples screens when using multiple screen sharing

I would like an option where we can decide the placement of other peoples streams when in the muli screen sharing mode. Or have an option where when it is two stream we can either have them stacked or side by side. I have an ultra wide monitor and when I stream with my friends they say my screen is really small and hard to see because the two streams are side by side, but if they were stacked I think it would make it look better.
