Hi Kevin,
sorry, I was a bit in a rush. Got more time now.
Regarding the Helix: we get 33,000 delta updates per second for this use case:

You can try it here (Desktop, scroll horizontally):
An easier example is e.g. the fieldset implementation:
https://github.com/neomjs/neo/blob/dev/src/form/Fieldset.mjs
In case we collapse it, we just remove container items from the real dom, but keep the JS instances and vdom alive, so we can change the state of child components while being collapsed. I will write a blog post on this one soon!
neo just got nominated as 1/5 "Most Exciting Use of Technology" projects inside the JS open source awards program.
You can find more infos inside the blog (fiends link collection): https://neomjs.github.io/pages/
Best regards,
Tobias
