I know PT and Realband aren't true scoring programs, but they sure have a lot of useful notation features. I use it to create music and generate the sheet music from it. Usually just a simple lead sheet.

The key things missing, for me, are the repeat signs and 'volta brackets (1st & 2nd endings)'.
Not asking to change the behavior of RB to follow the repeat signs, just being able to print out
the repeat notation would be extremely helpful in generating a simple lead sheet.
