Had a very quick play with the maps engine lite.
Got some pretty handy ways of visualising data from external sources (spreadsheets, google docs, etc.), rather than just a static “My Maps”.
Imported one of my Maps mostly OK, but loses half the pushpin icons and replaces with default though.
If that’s going to be the new maps, I hope they hide most of the editing bits until you want to actually edit/create a map. 99% of use is surely just looking at a map, finding destination and a route there?
edit: didn’t check bike routes, but assumed it was the same half arsed thing as before. will look tonight. tend to use opencyclemap for that anyway.
