For the margins, this is a tricky question.
I think there are two types of margins:
1. The margins I set on a file to make it look how I want in terms of spacing between the notes, I think it's less readable when they are spread too far apart. I add left and right margins on the file but this is not ideal because it depends on the format of my device and the idea is to be able to keep the same file for all devices.
2. The margins I would set differently depending on the device, because on my tablet notes are visible very close to the borders, but on my phone with a screen protector, they aren't that clear. These margins ideally should be additive to the ones set in the file.
I don't really like to set the right and left margins though, I would prefer to be able to set an aspect ratio for the score, like 9/16 for example and %%fit2page would then maximize width and height according to that ratio.
