It would be really useful to have a little more control of the blank pages that can be added to a song (or used to create a new song). 
It would be really handy to be able to add blank pages that have some stuff on them (like notation paper or lined paper) that might be portrait or landscape and of a specific page size. It would also be nice to be able to add pages in the middle of songs.

I have a workaround but it isn't very good. I have a few pdfs of manuscript paper (8.5x11 portrait and landscape) that I have imported as songs. I can copy a manuscript song, rename it something else, add a bunch of 1,1,1,1,1.... so that I can have more than one page, and save the new song. Finally, I can annotate some ideas using the pen or stamps. That method works for a new song but not for adding pages to an existing song. It is possible to add a manuscript pdf file (one or more times) to an existing song but you have to keep track where the pdf file is saved on the computer.  

Usually, when I'm sketching out a song on manuscript paper, the sketch will likely be temporary. (I use a notation program like Musescore to create a real version.) I'll add intermediate pdf drafts from the notation program to the song. I will further annotate the drafts with corrections and additions that need to be fixed in the notation program. Once I have a fairly complete version, I will add a pdf of that to MSP and delete the other drafts (though it might be nice to just hide them or turn off their visibility, if that were possible).
