The width of the code blocks in the answers is often too narrow and require horizontal scrolling

"Hot Network Questions" are a distraction and take up too much horizontal space.

Well worth blocking these with an adblocker, if you don't already

Don't even need to do that - just go to site settings and use the preference to block them - https://stackoverflow.com/users/preferences/current

It requires being logged in but you don't have to worry about empty spaces.

Didn't know this. Thanks!

Done, but now there is some empty space instead. Probably fixable with some custom CSS...
