Customise columns on the admin screens for posts, pages, media, comments, links and users.
Completely customise the administration screen columns with a sweet built-in drag and drop interface.
A default WordPress install only shows a few built-in columns. This plugin gives you many additional columns giving you full control over all columns for pages, posts, CPT, media, links, comments and users as well as add/ remove columns, change their label, change their width and reorder them.
Depending on the project, sometimes it’s important to customise the column layout giving your client what they want, rather than what WordPress gives them.
As well as the standard columns you can also add columns for page templates, post formats, taxonomies, ID, word count, roles, number of attachments, user ID, register date, biography, user custom fields plus a load, load more.
Seriously, check the plugin for a fuller run down.
The current plugin also comes in Polish and French.
