split screen are always good,
and more important now.

set up as an input an adjustable split screen,
where two inputs are selected,
and allow the user to adjust the split screen, either horizontally or vertically.
and drag each image into the best composition.
vmix will manage the zoom, pan and crop.

may be an overlay over the vmix screen
the final result becomes an input. have 2 or 3. even many!

user can then select split one, take one,
then select split two, and take split 2.

in essence, vmix becomes a 2 or even 3 ME switcher.

if this can be done while live, it is even better!
