I am updating the code to take into account the page color tone setting, as I did not handle that properly, but trying to use the "paper color" is a little trickier.

This is what I meant with "paper color". It was not my intention to use the "real" color of the scanned document. Maybe this is another point for not using some sort of whitespace above and below the line ;-) It would be much easier and more consistent.

In my testing, not having any divider created a lot of situations where I couldn't tell where one half ended and the other began. Yes the slider is clearly telling you that, but it still was unpleasant to see the two halves bleed into each other. You are not always going to have a situation where each half is between two staves.

I will have to test this with my scores. Until now I had (on my Max Lumi) a thick black line which was clearly visible. The new divider is much lighter, but I think I will get used to it. The fact that is movable is a big plus.
