Click box healer works just like healbot in wow or grid+the custom layout addon. It seems to sort the boxes the same across all windows, so if you line them up then you have easy mouseover click healing.

Profiles save to the file "Interface\Saved\ACCOUNTEMAIL\SavedVariables\Click BoxHealer.lua" inside your main folder, and obviously to line things up you have to copy across accounts.

I am having some quirks with the repeater regions right now but when resolved it should turn out nicely.
