A very simple mod for Hunters using secure action buttons to free up action buttons being used for your traps.
There is little customisation available as I wanted the mod as lightweight as possible. You can move the bar whereever you like and lock it in place. It will automatically scan your spellbook and only display the traps that you have learned. If you are not on a hunter, it will hide itself.
It should work for Bear Trap now, but since there is a blue post saying it is going to be canned, I haven't bothered getting anyone to test it.
