Problem or motivation

If you add custom classes to a component, its not obvious for other developers that they are there.

Proposed solution

Split the 'classes' pannel into two. The first would be as is, except you cannot add classes (probably only delete which would update the other panels as it works now). The second, new panel would be where you add custom classes. This allows adding and removing classes.

Optional nice to haves:

• In place editing of the class name
• easy copy of class name
• a small indication in the Layers tree that custom classes are added.
