Remove extra space by line numbers in Visual Studio 2015

Question

I have no idea if this is the right community for this question, so please feel free to move it if it is not.

In Visual Studio 2015, there appear to be six character spa

Answer 1

There are following margins left of code: breakpoints/bookmarks (17 px), line numbers (35 px), quick actions (18 px), file changes (10 px) and outlining (9 px).

I don't see any deliberately wasted space and I don't see any public options to change width of existing elements.
