Another addon you might want to look at is
Auracle (De)Buff Monitor : WoWInterface Downloads : Ace: Buffs. Its advantage is that it let you group several buffs of the same category. So instead of displaying two icons for Blessing of Might and Battle Shout you can group both buffs and label the icon "AP Buff" and make it disappear if the buff is present.
Both Auracle and BuffEnough have their disadvantages though.
Auracle doesn't know anything about the capabilities of your group and will complain about missing Blessing of Kings even if there is no Paladin.
BuffEnough DOES know the capabilities of the group but needs mouse over to show the missing buffs in the tooltip otherwise it only shows its "something is missing"-color and it isn't possible to see what is missing with one look at the UI.
