Will the snapping work with multiple Monitors?

Wow, I don't know. Didn't even think about that. I don't have multiple monitors to try it with and debug.

Snap to top and bottom of screen and to top and bottom of remote/face will most likely work. Snap to all screen edges on the first monitor will work, but snap to left/right screen edges on the second monitor will most likely not work. Hmm, if the second monitor is a different pixel height than the first monitor, it might try to snap to an invisible line corresponding to the top and/or bottom of the first monitor.
