I think that the menu links on the Admin page (eg. Dashboard, etc) could use some AJAXish updating.
I think it'd be useful if, when you hover over one of the Items, lets say Blogroll, that the menu line under it would then have the items for Blogroll scroll down in place of the current ones. So you'd then be able to go directly to one of the pages, without first having to click on Blogroll, and wait for the page to load, and then click it. Then, when you move your mouse away from the menu bars, the items from Blogroll would then scroll back up to reveal the current items.
It'd save time and allow the Admin panel to be more "flowing", and easier to use.
What do you think?
