@olf, no criticism taken . I'll take it as a list and reply accordingly.

I will have to look at some point on what indicators/buttons do we miss. It maybe easy to add the most important ones.

Different map modes are coming and I have an idea on how to implement it. Now that's 2-phase process - one is to organize showing them in Pure Maps and the second one, for offline, to make these modes in osm scout server. Latter will be probably iterative and would require feedback on which data to show and at which scale. Here we will lack the scale of userbase, I presume. But one must try.

Compactness of datasets has been essentially a price we have to pay for the approach used by osm scout server. Since I offloaded lots to Mapbox and Valhalla, I have to carry parallel datasets as a price. That will be better for OSMand and others single-app developed dataset projects.

I am surprised that you find offline routing by OSMAnd faster. Last times I tried, it was always slower than Valhalla. Will probably have to check again, thanks for a tip.
