Do You Use a GM's Screen? (Patreon)

This week, it's a jolly simple question! I'd be very interested in if you (generally) use a GM's screen when running your game. 

As a bit of background, I'm considering a line of GM screen-style products designed--as always--to help you run your game with less stress and more fun detail and I'd love to know where you stand (metaphorically, not literally) on GM's screens.

Thanks very much, in advance!
