On my laptop each take lane uses 1/2 inch of space
 
on the main computer more than 3/4 inch
 
given the significant amount of "uncluttered" space in track lanes

move the add/del buttons to the right of the record button

replace the menu with single click buttons that show state like the M/S/R buttons
menus are inefficient and clutter-up the interface
