Make the section break have a "no line break" tick box
It looks like the line break is hardcoded into the section break. With this option (in the inspector), there could be section breaks inside systems without them automatically creating a new line.
1) Add a section break in the middle of a system
What happens: All following measures go to a new line
What should happen: If this new "no line break" checkbox is ticked, the new section should start in the middle of the system, without a line break.
