Hello,
I'd like to present a Maya animation tool that I have been developing for years. I called it LMpicker.
LMpicker is a Maya tool to select your character controls with simple and intuitive mouse gestures, letting you animate in a clutter free viewport. It has been developed and used on professional environments. And the best part of it is that LMpicker can be used with any rig.
Please, have a look at the videos and let me know what you think. I think you will like it. :)
