Noted that Apple packaged Dashcode, the most productized widget-creation tool with Leopard.
Played with the workbench a couple of minutes, and was able to craft an RSS-viewer widget for this very blog.
Shocking. Speed-wise, that is.
But the widget does not render images, so everything is not at all perfect with it right now. And it certainly will not be published until that immediately obvious shortcoming is fixed (if ever).
Stay tuned, for exciting announcements about further adventures in widgetstan.
