Simple Gemcutting UI addition

Please add a toggle or category (like the weapons) for "equipped gems" to make it easy to see if you are able to level up any of your current gems.

Playing hybrid builds that uses different "weapon types", it becomes increasingly frustrating to have to search for individual skill gems each time.

If this already is a feature, make it clear how to do so, because I can't be the only one not seeing it. ^^
