Enhance your admin overview screens by displaying icons instead of text labels in the table header and footer.
The Icons Add-on for Admin Columns adds functionality for displaying icons on the posts, users, media and comment overview screens, and any other screens Admin Columns Supports. It supports all column types that have a label! You can choose to select one of WordPress’ native <a href="https://developer.wordpress.org/resource/dashicons/" rel="nofollow ugc">Dashicons</a>, upload a new icon image, select an icon from your media library and choose a custom URL to retrieve the icon from.

This is a little plugin which adds a featured image column to WordPress. It automatically adds a column to any post type which supports a featured image. The code is pulled almost directly from my plugin <a href="https://wordpress.org/plugins/display-featured-image-genesis/" rel="ugc">Display Featured Image for Genesis</a>.

Add Featured Image Column

If you have ever been like me and kept having to open up the posts to see what featured image was attached, you won't be doing that anymore. This is a "must have" download for all my installs.



This is a great plugin!

Works great!

It's a simple plugin, which does what it says and solved the need I had.

However, as it is not configurable it is limited. For example, there are plugins that add a thumbnail to their CPTs and putting this one in comes out both thumbnails.

For this and other reasons I have created a plugin based on this one that allows you to choose in which CPT the image is shown, besides customizing, shape, size and other improvements.

It is Manage admin columns



It does what it says

This plugin adds a featured image column to any post type which supports featured images. See which posts have a featured image at a glance!
