I've been playing tonight and *think* this is the add-on that was causing some of my problems. I couldn't use the bank and several keys properly without logging out. I couldn't withdraw/deposit gold and the escape key wasn't working. I disabled all add-ons and then tested the likely culprits (Wykkd's stuff) and then this one. I think this one was the problem which would make sense.
Can't wait until a new release is out as I can't stand the default filters. The creator of this add-on made the icons so much like the game it seems like it should have been a no brainer for the game to have this to begin with. Until then... I'll have to waste untold minutes sorting between light, medium, and heavy armor between my alts. Ugh
