Now, that's awesome. Now, authors can concentrate on creating themes, to innovate the way of showing content, and not the way of creating it (which is plugin territory).
Now our buyers can install a beautifully crafted theme, install a page builder and a shortcodes plugin, and use that for content creation. So now, when changing themes, there won't be the need to actually rebuild your website just because you have changed the theme.
Beautiful work you have done there. Good job!
