Seems like a neat application so far.
There's one thing though that would make this application even more interesting in my opinion. One Click program launching. Shortcuts in the fence still behave like normal shortcuts. I'm sure some people would like to keep it that way, so an option to switch between double-click launching and single-click would be the perfect solution for everyone. That way it would behave like a launchbar for those who want that. Right-click behavior should still be the same though.
Wanna start Microsoft Word in the fence? Left click it and it starts.
Thanks for listening.
