An easy way of telling apart different installs of WordPress ( e.g. live/production/local ) via the admin bar. Super admins see a colour coded machine name in the admin bar, with an IP submenu. Mobiles will see a colour coded square dot

Local Indicator

A fast way of seeing which machine a WordPress install is running on.

What The File adds an option to your toolbar showing what file and template parts are used to display the page you’re currently viewing.
You can click the file name to directly edit it through the theme editor, though I don’t recommend this for bigger changes.
What The File supports BuddyPress and Roots Theme based themes.
