Sometimes the motion path representation interferes with seeing how pieces fit together. I'd like to be able to make it invisible with a key command. Can this be done?
There's isn't currently a keyboard shortcut or UI to hide a motion path - this is a good idea for future functionality though! I'll make sure it's recorded on our enhancements list.
In case "always show motion paths" is selected and motion paths are on for every tween (this can certainly get in the way!), you can turn that off from the Motion Property inspector options menu.
