Feature Request. Stop Playback Button in Motion Window.

[PhilMassey]

Is it possible to put a stop playback button in the Motion Effect Window. The only way to stop is to cancel the window completely.  Pressing the play button again or pressing the spacebar just restarts play.

Whenever I want to work on a Motion Effect, I mute the sound and loop it (within the Motion Effect Window).  This allows me to work on the Effect before I say OK and insert it into my sequence. If you are working on an Effect that takes a long time to play, a Stop button may prove helpful, but usually, I'm working on the motion effect itself.  Once I insert it into my sequence, then I can adjust the specific timing of that Effect.
