I still haven't found a button that minimizes/maximizes tracks. Used to be in top right corner, you could expand/minimize with same button. The only way I can make it happen now is dragging it to size. Sometimes when I drag a track to make it bigger, they all get bigger. I've searched through the manual under tracks, can't find anything?
Go to Track View in the help, then under Track View menu, check out Auto Track Zoom. When it's not enabled, the button appears in the upper right for expand/minimize. When it is enabled, you can automatically enlarge any track with the focus while minimizing others, or drag them to the same height. It's very helpful once you get the hang of it.
