The Rebuild theme is bundled with few additional recommended plugins along with the theme installation setup files. These plugin installation will be pop once we try to install the theme on the WordPress site. We can completely enjoy the features provided by the plugin along with the theme, but we should understand that for automatic update of the recent version of those plugins will not be allowed unless you purchase a separate license and enter the keys on the plugin settings panel, Theme bundled plugins will not provide auto plugin update with a theme option panel to customize all the front end theme. However new version of theme when available might be provided with a new version of the plugin bundled with that new version, which can be still used by the admin for updating the plugin.
