in my setuplayout. With
\showgrid I can see, that the space before and after a section is the same as before and after a subsection (3 lines before, and 2 lines after). But it would be nicer, if the subsection-title empty-space would be 2 lines before, and 1 line after, there should be a significant difference between the space around section and the space around subsection. This is possible with respect to grid=yes, indicated by the shown lines, but how?
