i'm trying out an add-on called click box healer. so far it seems to work a lot like healbot from wow. it's less plug and play than healbot was but customization is very easy. i just tested it in a black garden and it worked very well except that i haven't memorized which clicks i assigned to which spells but i was still top heals. if you have been looking for an easy healer add-on then this is probably worth looking at and can be found at curse
