My best suggestion is that you take a good look at the new plug-ins on Jari Williamson’s web site.
Jari has lately been very active, and developed new plug-ins that work with the latest Finale versions.
Some of the new plug-ins cover what the old plug-ins could do.
Other new plug-ins can do things the old plug-ins could not do.
You could also ask Jari.
