The challenge with the pinch-only method is that if you are in follow mode, it is very difficult to prevent going into compass mode. This requires re-orienting the compass and manual going back to follow mode. I have to do this constantly while driving to change the detail level for navigation, which has proven to be very distracting.
Perhaps there can be an additional setting for the gps button that locks orientation and allows you to pinch and zoom without leaving follow mode? Even better would be a small Bluetooth knob that would enable zooming in and out without having to fiddle with the screen while driving. This could be done by enabling the app to work with Bluetooth remotes like the Satechi Media Button (https://satechi.net/products/satechi-bluetooth-button-series?gclid=CjwKCAjwhLHaBRAGEiwAHCgG3iUOLTwF18HbxnDgV2gtZwKv6sYk9QaVOMrxXwFkWAJ6-u_iYUwFTxoCKyUQAvD_BwE)
For me, this is the only major (and dangerous) flaw in an otherwise phenomenal product. Thanks.
