@michaelbechtold: Panoramio cannot be placed to side panel, you have to use "Map Layers" panel
@balloni55: thanks for videos, I'll check it. And track record button cannot be hidden now, only in case you use bottom panel for a control of track record, not a side panel
@0709: hmm maybe I undestand. Point "Sprint" has icon incorrectly placed out of track, so I though it's just some point in the field. If it lay directly on a track, then it's probably correctly used as "Via point". And I probably understand how the line was created - BRouter computed route just on a road above green area (as I wrote, it compute route for a car! ) and Locus created direct connection to Via point.
About some settings for BRouter ... this is more general problem, not just in case of BRouter. Because there are missing some kind of "Routing profiles", it is not clear how Locus should recompute tracks that has no definition about it's original "compute" source, like for example TCX files. I have to think about it and offer some general solution, agree. Thanks
