Is there a workaround to prevent invisible rests taking up space
As discussed in https://musescore.org/en/node/301555 invisible rests still occupy space in the score. This can lead to difficulties in achieving a desired notation.
My particular case arose when trying to notate a clarinet + piano piece where the piano had a cadenza and the clarinet also had a note at the start of the measure. I used insert mode for the cadenza bar and had to fill the clarinet part with rests. The piece was in 3/8 and I wanted the measure to look like a standard 3 beats long and so I made the "extra" rests that corresponded with the extended piano part invisible, but as they took up space the clarinet part has a rather odd looking bar with a gap at the end.
Can someone cleverer than me suggest a way to avoid the gap.
If not, perhaps invisible rests should have a "take/do not take space" attribute.
