I think you should change the name of this resource.
This is not a free plugin and it's not the same as the old visual composer anymore.
They are now 2 completely different plugins and this title creates only confusion:
- WPBakery Page Builder (paid only, on Codecanyon)
- Visual Composer Website Builder (free version + addons, on their site)
Long story short:
WPBakery is a content editor, VC is a full page front-end editor (like Elementor).
It's the same developers but because of issues with Envato, they had to change names and split the plugin in 2 different plugins. One is used to only do content layouts from the backend, the other one creates full page designs from the frontend only.
