I have missed this:
I would like having the ability to insert empty rows to anywhere in a system plan. An example: 4 rows are filled - I need to add an extra row between row 2 and 3 for more modulators and filters.
It's a pain (gigantic 1st world problem) to add an extra row at the bottom and then move all the modules of the lower half to make space in the middle...

KNYST, as unicorn user you have the "swap row" function in your "edit" menu.
That should do the trick.
