Seriously, nested comment chains are trivially readable and replyable on mobile with this applied. Horizontal scrolling? I mock your horizontal scrolling. It honours user customisation through the settings panels now (including left and right user icon positioning, which the first alpha didn't) and I just dropped a bunch of Navbar 2 fixes for Android browers so hopefully that's better now too. And comment depth markers on mobile now work on comments without subject lines.
If I could just stick Navbar 3 on this, goddamn. But I can't, that requires more changes than I can do just in CSS.
