What is the enhancement in mind? How should it look and feel?

Please provide any additional information below.

1. Priests commonly use Shackle Undead using a CC macro.  This would be a good default option.
Left Click:
#showtooltip Shackle Undead
/clearfocus [modifier:alt][target=focus,dead][target=focus,help][target=focus,noexists]
/focus [target=focus,noexists]
/cast [target=focus]Shackle Undead
Right Click:
Shackle Undead
Middle Click: Focus Target
2. Buff Bar - Should support Divine Spirit (doesn't work) and ALT self-casting.  No option given to change buff bar, but it's a good start.
3. Drink/Food Restocking System for us non-mages?  I know there's an issue with mana biscuits overwriting highest rank food (still happens with my macros, there is supposed to be a 1 second CD)

And finally,
4. Food & Drink Button - This would be good for all classes (perhaps except warlocks)
5. The option to add more custom buttons would be nice.  I really think it's nice but I don't want everything on a circle like that one other addon.  

And if the "chat" and "Warning" system ever gets implemented, all I can suggest is /oom warnings and "I'm drinking" group messages

Also, custom button naming would be nice.
