Thanks for the reply. Indeed your observation that my proposal is sort of the complement to a function alerting when *entering *a specified area is correct and pertinent. The two are very close and this in my view should increase the usefulness of such a function and possibly the number of users interested. I wonder what qualification one needs to programme such a function. Can this be done by anybody in the Osmand communitywith reasonable programming background (in this case: what language to programme it in / what testing debugging environment exists ? Where to find the interface specs to Osmand ?) or is this a job for a limited number of programmers who work on the continuous official versions of Osmand (in this case: how to formally propose it ? How to find out about the perspective / time frame whithin which this could be done ?) ? Apologies if my generic enquiry on these issue is naive and if as a user of Osmand I should know this: I have tried to find out on the Osmand webpage but am not sure whether these indications are to be found somewhere there.... ***Ruprecht On Wed, Sep 27, 2017 at 4:51 PM, Max1234Ita <[email protected]> wrote: > > > On Wednesday, September 27, 2017 at 12:13:45 PM UTC+2, Ruprecht Niepold > wrote: >> >> >> I recently used Osmand on a sailing boat.
