Windows Vista only: Sidebar gadget I Forgot The Milk adds quick access to your to-do list right in your Vista sidebar.
Installing the gadget is easy enough—just download, add to your sidebar, and then authenticate the gadget with Remember the Milk. Once you've done that, you can choose which list you want to display and easily add tasks right from the sidebar gadget itself.
The configuration dialog has plenty of settings to choose from, including making the gadget taller—sadly you can't make it any wider, so your to-do items might be a little cramped for viewing at a glance. Overall it's a slick, useful gadget and a lot simpler than hacking your own RTM gadget together.
I Forgot The Milk is a free download, Windows Vista only. If Vista gadgets aren't your style, you can get Remember the Milk in Gmail, use Remember the Task for a standalone window, or just add tasks in a flash with Remember the Milk for Launchy.
