I tried the g15 mod, but unfortunatly all it did was use the 120 action bars already available by blizzard (and of course in my case already used) So that did no good.

Interesting find about the script to keybind. Although that may work, it looks too unfriendly for being able to play normally and then play to multi-box.
I'm thinking the best option from the ones presented would just be to use Bars 11 and 12 for my gkeys and just swap those til i learn to memorize them all. Maybe after i can keep them hidden :::shrug:: well off to learn more advanced macros!
