Alternative way of notating tremolo and...
Okay I have two question.
1. In the .png I've attached you can see some different ways to notate tremolo. Is it possible to notate tremolo as the first of the examples, with two half-notes and beams? I think i looks nicer.
2. I know this question have been asked before, and it wasn't possible, but it's long time ago, so perhaps something have changed in the meantime. Staff type change: how do I change the number of lines in a staff at any point? That means also having the options of a no-line staff (specially neat for long tacets).
