First of all - thanks for agUF. Small and neat. Yet, I have some suggestions for those, and I'd be happy if you comment on that:
* providing alpha control for frames - right now the values of alpha for selected and deselected is hardcoded, and with SOME backgrounds, it's unreadable. I for example would like the background of unitframes to be pitch black, opaque.
* make 'hp -> smart' for target frame smarter - if target is friendly, display -lacking, if enemy or neutral - curhp/maxhp
* some way for showing 'resting' and 'in combat'? While first is not that important, the other could be crucial in some situations
* an option to remove text shadow. It makes me crazy 8)
