Hi Wes sorry for my late reply- I was ill and out for the count.
Answering the question
Yes I do exactly that.
Probably the same as Dennis and Lukas
Normally a master ui bone with most controls attached , I often have child ui bone parented to that ( head UI mostly).
I actually tried having them unattached to the rig and having them in another ui window split screen , just like Lukas' storyboard method before your script.
THat method
almost works brilliantly.
The problem with that is not that it takes up too much room, in fact, layout wise, it's perfect.
The problem is that the split screen does not update in real time- you have to let go of the mouse before the character's position updates.
Not the ideal rig to hand off to another animator with a caveat, eh?
Catch 22.
