Okay, their stupidity is arguable, it's just that they're so simple it hurts.  But they just helped me finish a CSS job in record time, so I thought I'd share.  They're set up to let you speed through setting up your selectors and then add the definitions you're sure about.  Then you can insert lines and use tab triggered shortcuts to insert further definitions.  Hitting tab at the end of a rule builds a new rule, hitting tab at the end of a property:value; creates a new property:value; line.  I set up #-Tab to create a quick ID snippet and .-tab to do a class.  They do the same thing, it just works the way a CSS coder thinks (or at least the way I do).  

Lastly, I scoped the Insert Color command to meta.property-list.css and added a # tab trigger.  The ID tab trigger is scoped to source.css.  So if you're inside of a definition typing #-Tab will give you the color picker (with the groovy color shortcuts) and outside will give you a new id.  I didn't throw that into the bundle, I'll let you make that mod on your own if you see fit.

Side note:  Learning the CTRL-[alpha] navigation keys has been a huge timesaver for me.  Moving my hand over to the arrow keys was almost as bad as picking up the mouse!
