My first email didn't appear to send, so here we go with the copy-paste:
First of all, sorry for not understanding the docs, I hope you get it,
being a beginner sucks.
So, the questions:
1) How would I increase the spacing between piano left hand and right
hand, AND between systems?
2) How would I increase the minimum (horizontal) measure length, right
now it looks a bit cramped.
Also also, sorry for sending my previous email twice, it didn't appear
to send for the first time, and then it did.
Thanks in advance,
Sam
