Separate minimum time for when on external power and/or passive location
There are multiple reasons to not wake up and log more than every 5 minutes (picking the default for discussion). Three obvious ones are power for the GPS, data/power to send the report, and track density on the server (storage or visual clutter).
When driving and plugged into power, particularly if using GPS anyway, it makes sense to log more often. I'm not sure exactly what UI makes sense, but a suggestion is to have a separate "minimum time on external power" and "minimum time on battery". Or perhaps "minimum time (passive)", where the app will wake up and make a passive location request, and if recent use it. Having said that, I'd combine these and have "minimum time (power/passive)" that both only happens with external power and makes passive requests. Then one can set "1 minute" and get faster updates when driving with osmand on, and slower when not, perhaps even changing the regular minimum to 15 minutes.
