it's so far more like "what is a good fit for the paper size"
unfortunately, so it's not of much use for anything but the auto
generated street index

Tracks and named Waypoints are rendered when using the new experimental
GPX Track upload feature.

Level of details depends on the auto-calculated zoom level, so for
showing buildings at low zoom levels the underlying stylesheets would
need to be tweaked.

Or you could try the "Schwarz-Plan" overlay (last in the list), that
should render buildings as filled black rectangles at all zoom levels
as far as I remember ... so you'd have the base map without buildings
but then the overlay would draw them on top.

In the "Share" menue -- opened by the third Icon from the bottom -- you
can export the current view in PNG, PDF, SVG ...
