I've played with ExtJS a bit, but I'm not completely sold on it yet. It's pretty bulky and I'm not sure how well it works on mobile (that may have changed, though). Still, it has some nice features. But if I was to use it, I would also want to write Rockets functions to make the syntax easier and cleaner. Still, there's nothing stopping you from using ExtJS in Rockets today if you want!
