I also love this UI. There is only one thing I can see wrong and it may be something Im doing. Im a Ranger and I use tracking a lot. When I bring up Track window the circles with the colors for cons are not showing up. The ones that filter out say red mobs from the list. The buttons are still there but just invisible so I cant tell if they are on / off. A little inconvenient not knowing if a Red is around your blue as you run off to kill it. Its a minor thing to a majorly well put together UI.
Just looking for a fix to this or if I just need to replace old tracking window.
