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.

Yes, to clarify, this is exactly what I was talking about—styles posted on userstyles.org (and marked appropriately as belonging to GreaterWrong) will become available to anyone who visits GW and has the Stylish browser extension installed.
Since January 2017, the Stylish browser extension has been spyware that transmits every single URL you visit to its corporate owners' servers. Firefox has just blacklisted it; users of other browsers may want to disable it manually. I think there's a config option that supposedly stops it sending all that information, if you trust its developers to implement that honestly.
