I would really prefer that default layout numbering or “Renumber layouts” simply numbers them 1, 2, 3, etc, regardless of whether they’re score or part layouts. The reason I use layout numbers in the PDF export name is because I want the files to be listed exactly as they appear in the layout list. But if there’s a combination of part, score, and custom layouts, the numbering is confusing (IMO).
Rather than having mutliple 01 or 02 layout numbers (one for the first score layout and one for the first part layout), I think a simple numerical sequence would be much easier.
Thanks for considering!
