1.0.20-redefined time signtures don't show up...

in the ‘Used in this flow’ panel. this would be a useful addition to the program. there might be cases where someone would redefine how a time signature parses the notes it governs and have that change readily available (instead of recreating it de novo each time it’s needed).

At the moment, the ‘Used in this flow’ list filters out duplicate time signatures a little too zealously, and I agree that it should list separately time signatures with identical numerators and denominators but different beat groupings.
