Hi @Daniele
I really like this Pjax feature, it makes the website feel so fast!
But there are some enhancements that it should be care of, like compability with lazy load (images and other stuff like forms).
One use case:
We need to make a podcast website that audio should be played in the background while page navigation, the only way (as i know) is to use pjax!
So we have some worries about compability with lazy loads and performance!
Best regards
