Completely fill a music frame and hide barlines

Hello, all.
In this example, there are two things that I can’t find a way to adjust:

  1. How can I get the staves to line up all the way to the left of the music frame?
  2. How can I hide all the bar lines? (notice that each system ends with a bar line and that there is a final bar)

There are time when making tests, or creating sketch paper when I need completely blank staves (not even bar lines). The margin thing isn’t a big deal, but the bar lines are.

Are you wanting blank staves?
It is built-in.
