WowAce

For those looking for a slightly more recent version, there was an Alpha version posted on WoWAce on 10/16/2010: http://www.wowace.com/addons/my-bindings2/

Posted a ticket, but the author no longer seems to be working on this addon?

Alternative:
Better Key Binginds

Better Key Bindings? Ok, but where can you find this addon? ;-)

With myBindings2 r50:

Please add AceEvent-2.0

I think I fixed mybindings2 to work in WoW 3.0.3

I haven't found any other mods that would serve as a replacement to this one. I find it extremely unwieldy to use the standard keybindings interface, and may have to learn LUA just to update this addon (if I could ever find the time, ya know?)

I'd like to echo what Moo said "One of the small mods that silently work in the background that i can't live without."

Please update!

This is the best replacement keybinding UI out there . Hope its gets updated for wow 3.02

Any other options to replace this addon if it is not being updated?

Well posting errors here as seen by BugGrabber when I tried mousing over or scrolling the window which is blank.

Please tell me somebody will fix this to work with the current (and future) game versions. One of the small mods that silently work in the background that i can't live without. /pulls plug :)
