I just switched to mazzle UI and despite feeling a little sad over losing my Pitbull frames (so much information!!!!) I really love the package.
I have two suggestions though on possible additions to the package.
For threat meters... Omen works really well, and is event based instead of poll-based, which makes it much more memory-efficient than KTM.
For damage meters... I love recap, but I've always found it to be a little (well, ok, a lot) buggy for me. Recount is an Ace2 damage meter that's very similar and works great.
I've replaced them both in my setup, but I'd love to see them added so I can control them in the combat button of the UI.
my 2cents. Thanks for a great mod package!
