- Based off of tiles, instead of s2's 6-faced-cube thing. This allows it to be used with a lot of well established tools and mathematical formulas. Also much easier to reason about IMHO.
- Indexes points about twice as fast at the moment.
I also use s2, and it really is terrific. There are many cases where s2 is the superior choice (mostly due to its hilburt curve indexing scheme).
- Runs in browser, for client-side indexing.
