Elementor 2.0 is the next generation of our plugin. We wrote about it in this blog post:
https://elementor.com/upcoming-elementor-v2/
Elementor 2.0 will enable you to edit more than just content. Headers, footers, single post pages, archive pages, 404 pages, search result pages and more.
It will also have full compatibility with Advanced Custom Fields (ACF), so you can use ACF data anywhere using Elementor.
