Good to know. Does it have OS maps available? I've got used to gpxeditor now - I like the clean interface and the fact that you don't need to login - but might try RWGPS as an alternative.
Don't think so. 99% of my routing is on road so it's not something I use. I think Bing maps has an OS layer so perhaps that would do what you need too?
RWGPS does this kind of thing too. It has about 10 different map overlay options - Google, Sat, Topo, bike paths on/off, terrain on/off.
