For so many years I've wanted a Spotify app with a small window, good hotkeys, low resource usage, and that's just quick to navigate around. So I finally decided to build it. I've been using it myself and I'm very pleased with it ✌️ It's still in progress but very promising!

I think I found a way to make a React Native list component with significantly better performance than FlashList, with 100% javascript. I'm still testing it but as far as I can tell there’s no pitfalls or issues… It just requires the new architecture for synchronous onLayout.

I made a mistake in the LegendList comparison which made FlashList look worse than it is 🤦. But another mistake made LegendList look worse than it is too 😂. And I did another round of optimizing today, so it's still looking pretty good!

The first video is when scrolling at 1.3x, way faster than is reasonable. This video is at 1.0x. The latest optimizations are not quite stable yet, will release them this weekend!
