OT: I need a css style editor that is point-and-click (or copy-and-click) simple. (I currently use Stylish.) I need something that lets me select a paragraph, adjust a style, and it automagically adjusts the class/id style for the page. This light text stuff blows- and unfortunately it kind of biases me against his ability to determine "readabilty" even though that is completely unfair.
