Line width Medium?

I’ve been working to make the 3d view more usable and have found a few tricks. With the dark theme I’ve lightened the color 3d viewport very slightly. And made the edit wireframe pure black instead of dark dark gray. I don’t know if it’s because my monitor is 2560x1440 but the wireframes are just difficult to see. Thin is very very thing and thick is way too thick. It’s like they are designed for either 1024x768 or 4k monitors. Is there any hack to enable a medium thickness line?
