As awesome as CSSEdit is, there’s always room for improvement. The auto completion feature for properties and values is brilliant, but one thing that bothered me was the absence of a few properties and values. Luckily these properties and values are stored in a .plist file. What’s the big whoop? Well, you can edit that plist file to get (almost) exactly what you want from the auto completion dropdown. Warning: Make a backup of your plist before you go willy nilly mucking with it. I cannot be held responsible if you mangle your plist! Please read the notes at the end of the post regarding plist editing before you edit your plist. Always make a backup!
