If you work on a mac and use textmate to code your WordPress themes/sites, please check Yoast’s textmate WordPress bundle, it’s a great time saver, very easy to use/trigger and most important very complete!

small tip for textmate: If you are using a dark-color as textmate background, try lowering the background color opacity in preferences to around 75%, this way you can see what lays below the window, very useful when you are working with photoshop to write CSS and have to remember a lot of pixel sizes ;)
