Skada is placed just under the Target/'s Target frames (which of course are hidden since I'm not targeting anything). I still need to fiddle with the bgc/transparency and find some kind of class/spell timer.
Here's what I roll with. Mouse-over actionbar with small buttons to the right, everything with key-binds are hidden. Large buttons to keep track of cooldowns.
Slightly modified caelNameplates. Rest is stock addons.
