Hi,
I often have to use pose tool in animation instead of using IK and after posing a pair of bones (for example) and many more...i have to choose over and over again the same pairs of bones to pose , it will be quite annoying if I have many pairs of bones because then it will be quite difficult to choose the right pair of bones I need.
So I suggest a solution, when I select a pair of bones to pose, I can press ctrl+alt+s (for example) so that the red circle controller is always visible even when I select another pair of bones (like saving it's in a library), and so next time I won't have to select that pair of bones again, just click on the red circle controller that was "created" before, if I want to delete it I can press ctrl+ alt+x (example).
