When I load an existing GPX file from the Tools menu to display a recorded track, the width is very narrow (maybe just 1 pixel wide) and hard to see unless you zoom in very close. It would be more useful if there were better control over the track properties (color/ width) or the track could be displayed in a similar manner to a calculated or loaded route.
Thanks. When I change the track color from Settings > Map Colors > NMEA/ GPX reply highlight, then return to the map nothing happens. After some experimentation I realized I had to exit the app & restart. This is a bug.
In album.style I found a section called editor type="line". I changed "line width for detail zoom" & "minimal line width" from 0 to 1. This seems to have increased the width. It's not a user friendly way of changing a setting though.
