This!ISBoxer/Innerspace has a really nifty feature that the others don't and that is cursor broacasting. I don't mean click broadcast but it actually shows the mouse cursor on each screen.
I got into a bad habit recently of constantly changing my UI...to the point I couldn't remember the keybindings so devolved into a "click caster". I'm slowly retraining myself, but this allows for my lapses into clicking on stuff.
It does take a wee bit longer to get setup than keyclone did, but from my limited experience so far it is very powerful. That being said....keyclone is still great. In fact the only reason I decided to try innerspace/ISboxer was because I wanted something that would allow my both warlocks to cast rain of fire at same time onto the same location.
