Here’s a suggestion for easier meter changes.
When I find myself frequently changing meter back and forth in a given section, it’s usually with the same beat value: 3/4 and 4/4, or 6/8 and 9/8. Sometimes I can enter a single popover value for alternating meter (like 6/8 + 9/8), but it’s often not that strictly formulaic.
It would be quite helpful if, when entering a meter change via the popover, one could type a single number, which would imply that the beat duration was the same as the previous meter.
For example, If I had been in 6/8, typing “9” would imply 9/8. It’s a little thing, but it would add up. I can’t think of a syntactical conflict.
