I'd like to recommend a very useful addon called IHML.
It makes daily quests much easier and also certain raid bosses where macros are useful. "IHML will save all your boss macros and swap in the right one whenever a BigWigs boss module is enabled. It can also swap by zone. IHML will only use one macro slot and will work with any action bar addon that you can put a normal macro on."
It also has a lot of predefined macros already configured. It works perfectly. Go get it!
