Two recurring thoughts: when we need to create a single bar of differing meter in an otherwise static passage (e.g, 1 bar of 2/4 in a 4/4 piece) it’d be great to have a means to do so in the popover without needing to reestablish the former meter afterwards. Perhaps a markup like “2/4:” or “<2/4>” would do the trick?
I’ve also wondered about creating a simpler means of changing meter when the denominator value doesn’t change; typing “3” to switch from 4/4 to 3/4 instead of needing the complete expression.
