Hi! It looks like I'd forgotten to update the CSS in one portion, due to this, on medium-sized screens, there was an overlap that occurred. This should be fixed now.
You can click on the hamburger menu to hide it.
Nope. Reader mode also doesn’t work, which is rather uncommon.
What browser are you using? On mobile Safari, I don't see the sidebar, and in Safari on macOS I can hide the sidebar. Reader mode doesn't work on either.
Reader mode should be working now. Just tested on mobile Safari.
