REQUEST: Zoom all tracks to fit timeline window

For some reason, the old track heights seemed to work 99% of the time. I've rarely needed to adjust track heights until now. Track height presets don't fix the problem and seem to be for a different purpose. 

REQUEST: Zoom all video + audio tracks to fit timeline window

• 'Zoom tracks to fit' = Fits the height and width of all tracks to the timeline window
• 'Zoom track heights to fit' = Fits the height of all tracks to the timeline window
• 'Zoom timeline width to fit' = Fits the width of all timeline tracks to the timeline window
• 'Zoom video track heights to fit' = Fits the height of video tracks to the timeline window, leaving audio tracks as they are
• 'Zoom audio track heights to fit' = Fits the height of audio tracks to the timeline window, leaving video tracks as they are

I currently use the \ key to fit timeline width but it needs to be consistent with the other proposed fit commands, so they're grouped and easily found.
