Request : changing constellation line thickness

Hello,

I need to change thickness of the constellation lines.
For example, sometimes when I show the constellation lines to my students at my primary school, they seem to not see well.
So, I'd like to change the thickness of the lines by some sort of user interface. ( I think it's appropriate to provide in the "sky and viewing option"　window. )

Thank you,
