Is your feature request related to a problem? Please describe.
Sometimes I find that the outlines of the blocks that are rendered are quite thick, especially noticeable when the blocks are farther away from the camera and thus the outlines look a lot thicker in proportion to the size of the cube.

Describe the solution you'd like
It would be great if there was a setting for this called something like "Outline Thickness" that could be tweaked to be made thinner (in my case) or thinner (for accessibility). I noticed that this is hard-coded into the renderer and it would be great if we had more control over it.

Describe alternatives you've considered
Perhaps making it so the lines get thinner (and maybe more transparent - but not sure) depending on how far away they are from the camera. Could also be related to the distance that you've already got set up in the gui.

Additional context
I don't have any screenshots, I forgot about taking those. :/

Would be amazing if you implemented this - thank you!

I s'pose this isn't really a huge problem/issue - it's just an idea I had while exploring my worlds. Accessibility would definitely play a big part in this suggestion - as well as customization - so I'd understand if there are more important things to be working on.
