Decided to make a light, custom healer UI.
I call it, "Out of the Box UI" because well, all your info is in a center box :O
I don't have actual raid or party shots at the moment, as it still needs some polish, so you'll have to make do with pitbull's config mode.
Idle
Party
Raid(10 man only, as I only heal alt 10 mans, but, with some scaling you could probably make 25 work to.)
Some note's -
Players pet and focus target are only there off to the side because of pitbulls config mode, i'll probably never use focus, and i'll fix pet later if i ever really need to.
The red bar is of coarse visualheal, looks weird, but it's just because i have full HP. this shouldn't happen in practice.
Trust me, it looks better without those icons that come from config mode, it really does fit.
Target window is set to deficit, so it fills up red instead of depleting.
All Buttons are hidden till mouseover.
