Is it possible to add a left bar line to the beginning of each system (one solo player)?
I’m afraid not, but it’s on our list of things to add as soon as we can. (I’m afraid this will also not be included in the forthcoming version 1.1 update.)
Has this feature been added in 2.x ?
It hasn’t, I’m afraid, but I’ll see whether it’s something we can squeeze in to the forthcoming minor update.
