Nice stuff but I’m affraid it’s to complicated for the average designer
But that aside. What I’m missing is the option to add opacity to background images. JPEGs are used quite a lot in webdesign, but they don’t support alpha channels (go figure). I’m not entirely sure whether or not it’s usefull.
Another thing. When I looked at the border-styles I saw that the dots where in fact round unlike current implementations. Could you add a class called squares or something alike (that shows like current browsers show the dotted style)
Last thing. When I define multiple colors to a border it’s, as far as I know, *not* specified which color the corners (where the borders overlay) should be.
