I have the previous Dell multi-touch screen and use it with MC. It works adequately, but it could be better with multi-touch support etc. Continuous two-finger scrolling in theater view (even standard view) would be most welcome. The "flick" is kind of hit-or-miss for finer scrolling.
Zooming in and out by 'pinching' would be nice too.
MC16 has introduced a ton of new stuff, so I'm going to wait patiently for such cosmetic additions.
