This is something I've been tinkering with for a while, but I think it's now complete enough to be generally useful. It's an alternative frontend for LessWrong 2.0, using the GraphQL API.
Features:
- Fast, even on low-end computers and phones
- Quickly jump to new comments in a thread with the "." and "," keys
- Archive view makes it easy to browse the best posts of years past
- Always shows every comment in a thread, no need to "load more"
- Log in and post using your existing username and password, or create a new account
- Simple markdown editor
- Typography enhancements
- Switch between fixed-width and fluid layouts and several different themes
- Easily view a comment's ancestors without scrolling by hovering over the left edge of a comment tree
Thanks to Said Achmiz for designing the themes and writing much of the frontend JavaScript.

I am 100% unsurprised that preferences on these things vary :-). I do like light-on-dark in many contexts, but high-contrast light-on-dark using "ordinary" body-text typefaces always looks terrible to me (Bad Things, to my eyes, happen where the strokes are narrow). For e.g. monospaced typewriter-like text in text editors, light-on-dark works just fine for me. I mention all this not in order to try to provoke any changes; just musing, again, on how preferences vary. Incidentally, the green borders on new comments are super-duper-prominent in the light-on-dark theme; you might consider toning them down a bit.
I wasn't expecting my tweaks to become an all-new GW theme (though I guess if there's a sudden clamour from users who try them and love them, anything's possible).
I don't have PHP installed on anything convenient, and don't think I will bother installing it just to make a small optimization to the appearance of my GW style.
