I just downloaded GhostBarMod and I'm liking it. It's a great place to store those seldom-used ability icons, like tradeskills or DPS call macros, pulling macros. They can be brought up, clicked, and sent away with the touch of a key.
I'd like to see GBM become more customizable in terms of the button layout. Right now it's a big square; it would be nice to configure the buttons differently... like two large center icons and other smaller ones around them, etc.
Thanks for the mod!
