WellRounded Dreamweaver Extension

"WellRounded is a Dreamweaver extension that creates easily resizable rounded rectangles you can use to frame your content. The rounded rects are not single static graphics, they are sliced graphic pieces in combination with modern CSS code. WellRounded generates an infinite variety of looks based on your choice of color, stroke, border, drop shadow, corner radius, etc. Once a rounded rect is added to the page you simply type or paste content into it..."

This looks like a handy little niche-market extension, I'm certainly going to try it out.
