Styling the background color, heading tags, links, etc. is just the start of what we're considering with this tool. In addition to create CSS rules for all the basics you mention, we'll also create a consistent look-and-feel for lists, tables, form elements, and so on. Moreover, it could protentially style all Spry (or other JavaScript framework elements) layout widgets, like accordion panels and tabbed menus--in all the various required states--for you, so they'd fit into your site design. This tool would also tie into our other extensions, so you could, for example, take a CSS Sculptor layout that you'd created and extend it's design style to the rest of the elements in your site or, conversely, you could take a design created in this tool and apply it in Sculptor. Same two-way functionality with CSS Menu Writer, SiteAssist Pro, DataAssist, eCart, etc.
Does that sound like something you could use?

P.S. Be sure to take the survey, if you haven't, to see what else we're considering.
