I just ran into two nifty web design helpers:

ProCSSor – ever edited your CSS in Dreamweaver, Notepad, Notepad 2, in-browser editor and some other program at work you don’t remember?  Then you know what it’s like to see your CSS go to pot.  ProCSSor re-prettifies your CSS automatically.

Maki – an app that you access via bookmarklet (I love those!) that helps you slice up your Photoshop design into CSS and HTML.
