Thanks, not as yet. It startes snowing here last week :-D I am definietally planning to test it once the weather will allow me to do so. I will share short update video then. ;)
I think there is option to follow terrain according to gps elevation. But I dont remember the name of that button. Its in the settings of follow me mode.
I never tried but I woudlnt recommend it. Mini 2 doest have optical zoom, it only crops the footage, so I would better crop it in pc, in postproduction so you can better control result. :)
