Hi my favourite notation software!
I wish there could be a way to insert a mark between the systems in a score; it aids a lot in tracking where one is looking. I used to use another piece of software (not anymore since you arrived :-) ) where a caesura mark appeared at the left most column in between the systems. This is especially helpful when empty staves are hidden.
Keep up the good efforts. <3

System divider? Press 'Z' to add to the score or Format->Style->System dividers
Definitely use the option Format / Style / System, it's completely automatic. The symbol works too but would be a ton of work in comparison.
