Trapper

This addon frees up the use of up to 5 buttons that will not be needed to place your hunter traps. You get a "bar" in the shape of a bear trap that has the five hunter trap buttons on it. The buttons configures itself depending on the rank of traps your character has and the number of traps. IE: A level 1 hunter will just have the bear trap image as you do not yet have any trap spells to cast.

You can move the trap "bar" by just dragging anywhere on the bear trap image.

This addon was created during the Burning Crusade era and has been working and thus tested ever since.

Still works with 4.2 but I haven't gotten to it seriously to fix it to work with the trap launcher.
