"improving" is very opinionated here... i'm sure some would like to simply remove the max-width, but makes the comments much less legible.
Came here to say the same. Always bothered when line-length is too long.
Not a big fan of this. Eye movement is much higher with this redesign. As a coder you frequently check last edited files and folders. To do this you have to jump a lot with this version. Just because you have available space, doesn't mean you have to fill it. (https://blog.prototypr.io/importance-of-white-space-in-design-5a40c0e65bfd) The default design looks like a list (what it is), your redesign make it look like a webapp with higher complexity.
Also the brain (at least in Europe and America) is trained to conceive content from left to right ( F shaped pattern -> https://www.nngroup.com/articles/f-shaped-pattern-reading-web-content/ ). This way I instantly get caught on the information I don't care at the beginning (About section, used by,...).
You also have way to many characters per line. Not easy to read. Scrolling is nothing bad.
