Background Image Cropper

Adds cropping to backgroud images in the Customizer, like header images have.

This plugin is a WordPress core feature-plugin that adds cropping to background images for parity with header images. For this particular feature the implementation is quite simple, but it's starting out as a plugin to gauge user interest in this feature and whether the feature improves the user experience of background images.

This plugin requires WordPress 4.3 Beta 3 or later.
