Yeah sure the new design makes poor use of screen real estate, but the deal breaker for me is the memory consumption and extreme lag when using it. I find it extremely surprising that Facebook’s flagship product fails to leverage React’s optimizations.

For me, the chat has started lagging a lot which is strange since it was the pioneering ReasonML project, which they praised a lot after the rewrite.

I could easily see this used to reliably decide the rate of opening / closing businesses and public places on a local scale if automated and implemented on a large scale. Thanks for sharing!
