This utility plugin changes the theme of the current user to Sunrise, and uses the Sunrise color scheme when browsing the front-end, to help ensure you are viewing and editing the Development Site when making crucial changes to a site.
This plugin also adds a menu item to the admin bar to further confirm that you are on the Development Site.

“Quick Empty Trash” is a small utility plugin that saves you time when emptying the trash for any post type. It adds an ’empty trash’ button to every post type’s list table, so that you can empty the trash for that post type without having to load the list of trashed posts first. This helps if you have a very slow-loading dashboard or if you just feel like saving yourself an extra page load in order to perform a simple action.
There are no settings to configure – just activate the plugin and the button will appear for you.
