agree, but I think that the Mac ver is still in "catchup" mode from that loooong period in which we only saw v12.

As for needing a leadsheet being a "must have" for copyrighting, I would disagree on that point and so does the US Copyright office. Although different countries may have different submission constraints, most get together every so often to create an internationally even situation.

We can still submit sheets but can also submit as recording, etc. and get the same treatment.

I submit sheets when it is an arrangement, score, etc. but I can't use even the Windows version of BiaB for that, because it is not a fullblown notation software suite anyway. Sibelius rules.

The Windows version of BiaB comes in very handy for creating fast Leadsheets and Fakesheets to pass out at combo rehearsals and the like, though and I feel that the Macintosh version sorely needs that feature as well. And if you want to submit to copyright office as fakesheet, you should have that feature.
