Rofl, having used lunarsphere briefly it won't be easy, assuming it is possible, as when the button is expanded it extends beyond the confines of the frame. Healbot is similarly afflicted if you have a big setup like I do
But, if like I do with healbot you just want somewhere to hide it when you don't need to use it, then assuming as above, it shouldn't be a problem.
Rofl, but I don't want to hog all the info panel plugin ideas
So I will leave it a while to see if someone else wants to have plugin fun
