I've been using it. The reason I came back was to try it. Well.....it's not all that great. It looks a little better than KR....it runs a little...and I mean a little....better than KR.....but the most common thing I've noticed is a little popup in windows that says, "UO Stygian Abyss has stopped working." It's a memory hog with enough leaks to kill a person.
But the interface is decent....and I think it's a definite improvement over the abortion known as KR. Fix the memory leaks and it could be a winner.
