Save your Action Bar using this free add-on for WoW
Version: 2.2DaemonSaver is an add-on tool that lets you save your current action bar settings, selected talents, and equipment settings. You can save up to six slots with just action bar settings, just selected talents, just equipment settings, or any combination of the three. Each slot can also be named for later reference so you can know what has been saved in the slot.
Operating System: Mac OS X
DaemonSaver was created in order to make it a lot easier to respecialize (respec) a WoW character. For example a priest who wants to switch back an forth between Holy and Shadow could spec Holy and save his/her action bar settings, selected talents, and equipped items in slot 1 and name it "Priest Holy". He/she could then spec Shadow and save his/her action bar settings, selected talents, and equipped items in slot 2 and name it "Priest Shadow". Now at any time he/she can reload those settings from either tab.
Note: You must first unlearn your current talents from your class trainer, before reloading saved talents. Yes, it gets more expensive each time you unlearn your talents but the cost maxes out at 50g and then eventually starts to go back down, and so on...
