Ah, I see. I never used that in Google Maps so I never noticed. It's not a problem, if the next issue is addressed.
yes, I was using this. when you do that, it zooms out. So, if I get the map to look like I want (e.g. the cache I'm navigating to, within 500 ft, and I are in the map) and I want to switch to the mode where it points me in the right direction with the rotating map I can't do that. Hitting the location button zooms back out and changes the mode. once I get it back to rotating map, I have to zoom back in - and make sure not to pan at all or I have to do it all over again. as far as usability, I only really noticed the issue when I was close to the cache.
iPhone 6. just used to geosphere where many 1000's are handled without an issue. it wasn't even a gpx file, I just hit the live refresh until there were about ~1000 caches and tried to add to an existing list which had about 500.
that would be my preference, although I can totally see people thinking it would be too cluttered.
thanks for the very fast response!
