Reset average speed (on long press widget)

[rysson]

Describe the idea (required)

Very small change – I propose reset the current value in the average speed widget on long press.
After reset average speed should be calculated from the beginning (like on the app start).

I could be useful for short time measurements, especially for average speed enforcement camera (until #13430).

Tell us about the expected behaviour (required)

On long press the average speed widget the average speed should be reset and should be counted from beginning.

Tell us about alternatives you've considered (required)

Current workaround is kill OsmAnd and start the app again.
It's harder if OsmAnd is running on Head Unit.
