When inputting a large block of text above the staff, Dorico automatically increases the system gap to account for it, unless the text is on the top system in which case it overflows outside the music frame. It would be nice if Dorico saw the upper border of the music frame like the bottom of a system, as this requires quite a few manual tweaks to fix.
Also slightly off topic, it would be nice to be able to set the order of system objects, for instance where the rit. coincides with the text. I would prefer to have the rit. closer to the music.
