Here's the thing, for $10 it would be well worth it to me *IF* I knew it would work better/easier than what I can setup with AHK.

On the other hand, I'm pretty sure I could write some wicked evil scripts using AutoHotKey that would further the twoboxing abilities such as checking to see if a hotkey is on cooldown or out of range by pixel color and then sending the appropriate hotkey...

But that would definitely be dancing on the EULA naked with a "I hate blizzard" sign tatooed on your ass...
