A better, user-friendly curveControl UI object.
I've posted before about my bitter struggles with the terrible curveControl UI object that ships with Max. Maxscript does not give you good access to it, it's very difficult to get it to initialize and remember it's settings from a previous session and if the control is not visible Max doesn't even "see" that the curve exists causing any scene objects relying on the curve for control data to crash, especially when a scene re-opens. In short, it is a piece of junk and Maya offers all kinds of ways to easily use curves to control rigs etc. The only curves in Max that are easily accessible for rigging and animation are the ones embedded in the Reaction Manager, but anyone who's used the Reaction Manager knows that that system is no walk in the park either. It constantly creates junk states that you have to sift through and manually remove, etc.
SO! How about a curveControl 2.0? One that's almost as easy to implement in your script as a spinner or a button? Would anyone be willing to take up this cause? I would say it is one of the most badly needed features as far as the animation/character aspect of Max goes.
How about it anyone?
