Will your team please add an undo fit vertically, as it hides all of the individual mixer controls. Because, I do not have time nor the patience to drag each of the several files down to master each individual track when editing several tracks, and the complete mixer makes it impossible to master the volumes if you have over 20 vocal clips on new tracks. Thank you. 
Don’t use “Fit vertically” when you have lots of tracks. Use “Collapse all tracks” instead (also in the View menu). There is an option to “Expand all tracks” which is basically an “undo” for collapsing all tracks.
“Fit vertically” is primarily intended for expanding a small number of tracks (1 or 2 tracks) to fit the available screen area. “Collapse all tracks” is primarily intended to minimise the vertical height when working with a lot of tracks.
