This is something I’m definitely going to use on client sites.
This plugin allows you to add whatever you want to the Dashboard through PHP and HTML and allows you to even add Sidebar Widgets. You may also wipe the entire dashboard or individually remove some of the more irritating sections like the Dev news, Planet WordPress and the getting started section.
That part about getting rid of the Dev news is great. I’m sure it’s confusing for clients to get to a Dashboard filled with all sorts of stuff that they probably will never read.
Compatible with WP 2.1.
