...."There's a new Widget Dock, which is exactly what you'd expect: a simple "launch bar" that can be placed along any edge or in any corner on your display. Widgets are managed there -- you can hide, delete or set preferences on any widget by right-clicking the dock. Yahoo Widgets 4 installs with a Flickr widget and a widget search widget. If you have a Flickr account, the Flickr widget can be set up to display your own photos through a simple authentication process."
..."The discovery widget is a nice touch. You can search for new widgets and add them to your stack right there in the dock."
