I like v25 so far. It feels faster and much more responsive. Haven't tried most of the new features yet.
But here is one I don't like:
In previous versions, creating a PDF file from the Print dialog would result in a default name for the PDF that matches the Finale file name. No extra typing or correction required. In v25 the score/parts print selection dialog has been moved into the print dialog, which seems to make sense. But now, when I make a PDF through the print dialog, the default name is "Untitled.pdf" = extra typing. And what's a bit more annoying the resulting PDF file name gets a " - Score" appended. Makes sense for an actual score printout but for a lead sheet? I often have multitudes of PDFs to export and having to manually go to the Finder and change "Title - Score.pdf" to "Title.pdf" seems like a waste of time.
