Just to close the loop: For the Midlothian Std. Nats, I configured a cruise page and a climb page, each of which maintains whatever zoom level(s) I set. I just toggled between the two manually whenever I stopped to thermal and again just before I rolled out to cruise again, or whenever I needed to check the big picture (zoomed out) view in a thermal.

I like TopHat a lot. I wish there were a way of autoinvoking the circling page while preserving the ability to quickly switch back and forth to the cruise page but I never could find it.
