Popular online task-manager Remember The Milk has added Google Calendar integration so you can see your to-do lists in your favorite online calendar.
The new feature adds a little check-mark icon to each day in the calendar. Clicking it lets you review and add tasks, complete or postpone tasks, and so on. It also works with Remember The Milk's recently added Google Maps integration, meaning you can see where your tasks take place--great for, say, planning an errand route.
You'll need an account with Remember The Milk, of course, but it's free--and if you're not already using an online to-do manager, you're sure to love this one. Thanks, Deborah!
