I've got LegendList's scrollToIndex and sticky headers features working in react-dom now (though not fully optimized yet) - try it out in @legendapp/[email protected] 🎉
If you've used another web virtualized list library before, what are your pain points?

Wow this is a huge improvement from upgrading to LegendList v2! I didn't even know it's THAT much better 😅
I've been using @habitpixel.com for a while and it will be great to get a perf boost in it 🎉. So cool to be able to make the apps I use even better 🫡

Just upgraded Legend List from v1 to v2 in @habitpixel.com, and wow, performance on my Pixel 4a just got a serious boost! Didn't expect this level of improvement.
Also tested Flashlist v2, but it’s more on par with Legend List v1 - kudos to @jayz.us 💪

I got maintainVisibleContentPosition working in LegendList on web 🎉
So it looks like we can support initialScrollIndex with no jank scrolling up, and bidirectional infinite lists should work too!
The solution seems to be scrollBy(), which does not break momentum scrolling 👍

I'm actually working on making a perfect chat UI right now. The answer to the list is Legend List of course 😅. But there's a lot more on top to get everything perfect. We'll hopefully have something to show soon! @samuel.bsky.team Ping me when you're ready and I'll try to help 👍

That's a good question! I hadn't gotten there yet. But I should probably experiment and figure out that pretty soon... I'll post back when I figure out the best option. Do you have any favorites?

Very interesting ideas I hadn't thought of!
- how do you define a group? Would it be by filtering for certain labels?
- showing latest comments could be very useful!
Mind if I ping you in a few weeks to talk more ideas? Busy with Local First conf and App.js for the next couple weeks 😃

Not yet, still a prototype. I'm experimenting with UI and haven't hooked up the write APIs yet. I'm going to try to release something with a month or so. Busy for the next two weeks with Local First conf and App.js :)
