But for starters it would be nice if they could just cage the mouse into one monitor
Aroddo. you can use an app called Ultramon to do exactly that. It has many other features too, like a functional task bar for the 2nd monitor, wallpaper manager,manage display profiles etc....
You can set the feature "Lock mouse to active Window" with a hotkey shortcut, works a treat.
It's not free, but i have found it to be worth the money.
Ultramon.
