Try selecting "New" and setting up the display to how you want it to look when you open a song file. You can have the Main Tracks displayed on top, but also you can set up other windows to your own requirements, eg Mixer default setting to show say 20 tracks plus 4 Group tracks. When satisfied, save the file as $Options.seq in the RB Root Directory and this file will, be loaded each time you open RB and each file.
