This sounds very promising, Robert.

Can’t wait to take a look at all that!

It has not been updated since 2017. It is gradually becoming incompatible with new releases of Finale, and it will stop working entirely under a likely imminent release of Finale for Apple Silicon.

(You can use FCCustomWindow instead. It's slightly more cumbersome to use but looks far better.) Also, the setup and development environments are completely different, though simple to use.
