OpenStreetMap improvements

What does happen when multiple maps overlap? Which one gets the precedence?

They're drawn in order right now - so the one furthest down the list of maps gets drawn last. Potentially the uploader could have a way of sorting, or maybe we just sort so the smallest maps get loaded last?

Also there could be a bug with the recorder app when a map is uploaded with size != medium there seems to be a x,y offset. Can anyone reproduce this?

Recorder app? Or just the maps themselves? What kind of offset are you seeing? I did try testing it with multiple overlapping maps of different scales/sizes and they did appear to match up ok, but I guess something could be wrong.

I did spot an issue plotting tracks from the OpenStreetMap app, but that's fixed now.
