Wow Addons - Cata

TBag is a WoW Addon that provides an alternative bag and bank interface.
 
I modified accessing the menu from the standard Right-Click interaction, to Shift + Right-Click.
It got on my nerves when I clicked just outside the bag slot(s), and the menu would pop-up while
vendoring quickly.

The TopFit addon for Cata 4.3 that I modified to allow auto-equipping better Bind on Equip items.
Instructions:
Hit, "C" key to bring up your character panel. In the panel you should see a drop-down box above your character's head. Select your desired build. Close the character panel. Hit "Escape" key and bring up your Interface panel. Select the "AddOns" tab at the top. Click "TopFit" from the left panel list of addons. Check both, "Show set values in tooltip" and "Show item comparison values in tooltip". Then in the "Automatic update set" drop-down box, select your desired build. Close the Interface panel. I suggest re-logging to save your addon data.
