Hi Steven - thanks for your kind feedback about the site and for taking out Ad-Free membership.
We use Google maps for our default maps and Open Street Maps for our Paths maps. Footpaths are coloroured grey on Google maps by default. I think there is a way for use to apply custom styling to Google maps but at a cost, so I'm not sure whether this would be viable. I've added it to our Feature Requests list (number 43), where users can vote for changes they'd like to see.
what mapping does plotaroute use, as footpaths, rights of way(uk) etc are colouted grey...or not there at all ?
Would it be possible to change the colours of these in the next update, so they stand out please.
Brilliant btw, and didnt hesitate to pay the small price to help this along.
