The people over at WordPress.org have just released a "Navigation Options" survey for your input on what the administration area's navigation should look like in version 2.7 (which is scheduled for November 2008).
Here's a link to the blog post announcing the survey: wordpress.org and here's a direct link to the survey itself: PollDaddy.com
It took me less than five minutes to complete, in case you're wondering how long it takes ;-)
