Thanks for your ongoing work on making the map (and service) awesome.
At least in Japan, the best map overlay I have found after much testing is https://www.cyclosm.org/. It includes detailed information on speed limits per-road, shows recognised cycling routes and also does a great job at classifying main roads which are prohibited for cycling.
It would be amazing if this could be used for the map display, or a setting could be added to choose which map source to use.
I noticed there was a request over in Feature Request: Mini-Map - #10 by CEscorcio but this was seemingly pre-minimap implementation, so hopefully posting this as a new thread isn’t a no-no.
