I’ve just uploaded a couple of plugins for the blogs on joshandmeg.net.
Both of these plugins change the way the admin area of WordPress looks. They can be activated independently of each other, providing a couple different changes. If you just activate Admin Drop Down Menu, you’ll have the standard admin tabs moved up to the top of the admin area and changed to mouse-over drop-down menus. This lets you get to a lot of admin areas in just one click and one page load, while maintaing the general look and feel of the admin area. However, if you want a completely different look and functionality, I suggest activating Fluency Admin and Admin Drop Down Menu. This allows you to still get everywhere with one click but moves the links to the left of the page and changes the color-scheme to a slate-gray and black feel. I am personally using that combination for awhile.
