Different Format for Page 1
It is great that MuseScore allows different page formats for odd and even pages, but I seem to always have problems with getting my scores to fit on the first page. (I write scores for choir and full orchestra.) Because of the titles at the top of the first page, the first system is often pushed to the second page. If I adjust everything so that I can pull it back to the first page, then usually all of the subsequent pages are pulled right up to the top of the page and have a bunch of space left at the bottom, which just does not look very nice. This also makes a big mess when you try to extract parts. I end up having to reformat the page for every part, which is a big drag.
It would be really, really useful if we had the option of setting page format for the first page and having it be different from all of the subsequent pages to account for the titles and text at the top of the page. I really appreciate what a good job MuseScore does with formatting and avoiding collisions in the music itself. In fact, I think it does a better job than Finale and Sibelius in this regard, but not being able to format individual pages is a big drawback.
