Show bass cleff should default to checked when opened song has notes in the bass line

My kid was doing the Adventure map and started with one of the stock songs, but wanted to change it. He was confused why there were notes playing that he couldn't see, so I had to tell him to make sure that "show bass cleff" was checked.

Seems like this should default to checked when there's music in the bassline, and people can close it if they want more space.

I agree if there is non default music in bass cleff it should be opened by default.
