Quick note: I'll add '[$]' to article titles from now on to indicate commercial content. I hope that'll help clarify things for everyone!
After using Blender on production work I've found the need to separate creation from use in order to minimise user error like building a rig then handing it off to an animation crew.
My first venture into this territory is an addon that only displays available unlocked channels for the selected object or bone to simplify animating.
I hope it helps every one in their endeavours and thanks for taking an interest.
