I have created an issue in the issue tracker for a new feature, I quote below:
it would be fantastic that the program allowed us to save separately the styles for the graphics and the styles for the texts.
For example, I would like to create templates with my graphic preferences (staves placements, margins, a.s.o.), and make differents versions of them with different fonts. With the actual system of saving, if I create 10 different versions of the same template with different fonts, and then I notice that I would like the margin to be larger or thinner, then I'm stuck, and I have to modify the 10 different styles files.
This improvement would be great ! :-)
What do you think about it?
