Finally converted all my code snippits into one large tool that I can use to increase my workflow speed.
Most of these tools were build while working on a certain rigging problem, usually once I have done the same step 3-4 times I will try to find a solution via scripting.
I have automated my biped base skeleton creation, controls creation and 2 repetetive steps that were too time consuming otherwise for me. (Creating Facial Curves for joint based face rigs and creating my nurbs surface deformers that I love to use)
