Animator controller

Will you ever add function to change Variables in animator controller when animation ended/started? (Really missing such feature, yeah i can use animation event but create script for this every time, rly? (+ some times animations skip some keys and you end up with glitches))

You can use behavior scripts on the state to do this.
Click on the state in the animator window and add a behavior on the state exit that sets the parameter to the value you would like.
