I'm certainly not advocating a full blown score editor or a way to print/share beautiful scores - just a staff editor that works. If you spend any time with staff editor as is, you'll come across lots of aggravating issues - try entering some lyrics and you'll soon want to throw your PC out the window!
Updating the component that the staff view was based on with the new version from Sonic Scores would probably address many of the issues, without Bandlab having to re-work the whole thing and commit a lot of development resource..
.. then again, it's never happened before, despite all the feedback and requests, so maybe there's a reason we don't know about.
