Some sort of dropdown to change styles quickly instead of erasing and re-typing the name of the class...that would be nice.
Example: I got a link with a blue color that occurs 53 times on different pages. I change the background color...and now I need to change the link color to red. Instead of ereasing the class, re-typing and selecting the newly created red-class, a dropdown to select it would make the work a lot faster. Especially when you also have nested classes..
Just my 2c.
