Great mod. Can't wait for the mouseover functionality to be put in.
I've found this bug with the keyring. I have it disabled as default but every time when I log in, the keyring pops back up and I have to manually enable, and re-disable it. This problem seems to exist mainly on my warlock. It might have something to do with Felcloth bags, because I don't seem to have this problem on other chars.
Also I have a feature request. Would it be possible to add an option to each bar that automatically centers it according to the user's screen width. I haven't seen this functionality in any action bar mod, pre- and post-2.0, and it's a very useful tool to have.
Keep up the good work!
