Plugins are awesome
WordPress Lossless Image Compression
Reduce the file size of images on your site as they are uploaded without loosing any of the quality. Reduced file sizes leads to lower bandwidth costs, lower storage costs and faster load time.
WP-Admin Colour Switcher
Change the colours of your wp-admin screen based on which environment your using. No more getting mixed up if your using development, staging, production or QA anymore.
