You actually can export your annotations with the latest version. Just long press the song on the library screen and select "Share->Export Files" and it will write out the PDF with annotations intact. As for MobileSheets being able to modify old annotations, that's something I have planned for the future but it's going to take a lot of work, as I'm basically going to have to convert PDF annotations back to MobileSheets annotations so they can be modified, then delete all the PDF annotations and replace them with the converted MobileSheets annotations.
