A classes manager similar to the variables manager for creating CSS classes with the ability to group/categorize them.
The class control under Customize could have a shortcut button with a list of all available classes for quick insertion.

I’ve used this feature on Breakdance and it’s AWESOME! You can right click to create a custom class with your class name of choice, then type into the class field and it’ll auto-match existing custom classes.
I was actually considering to suggest this, just a few days ago actually when I first reviewed the latest Cornerstone Beta. IMO, this would add another notch in securing Pro a GOAT status!
