Updating this back to "Planned" as all development work has been paused in order to resolve other critical and outstanding technical issues.

I will resume development of this in the near future. Thanks for your understanding! 🙇🏻‍♂️

I've started to look into how difficult it would be to add support for quintuplets. Some work is definitely needed to handle the beaming of these rhythms. Will share progress on these as development moves ahead. Planned for a future 3.x release.

5s (quintuplets) are slated for inclusion in a future release.
