I always though a good feature for Photoshop would be a way to select areas of a file and mark them as dynamic content and non image content, that way PS knows what all of the static content "or template" is. Then PS could analyze and auto slice the image and generate the template HTML file that you can then go back and add any non image HTML to. As well it wild be nice to be able to define groups on the template so that PS would slice them out separately for items that may be repeated on the page or that may be used on several pages. My thought was that all this could be accomplished by tagging a layer to be ignored for generating the auto slice.
