Simply adds the ability to define custom icons very easily for any custom classes via the project settings, without having to write tedious amount of C++ for creating a custom style.
Only limitation is for the icons to be applied the class / base class must be implemented in C++.

As of now I have no real clue how to support blueprints, as a work around you can create the blueprint class with C++ first and then create children via blueprints. (This is overall better anyway in general)
