The visual design of the group roll frames are heavily inspired by addons like XLoot and TeksLoot. The main difference is that my addon does absolutely NOTHING! I have not written a loot addon, nor a roll addon. I simply reskinned the default Blizzard loot and roll windows. And it worked like a charm. If it ain't broken; don't fix it. But if it looks like crap; pimp it!
And yes, my tiny 1280x800 resolution is a joke. Don't rub it in. Just download gLoot and be happy!
