Google Calendar went and made it official overnight, integrating the tasks list already present in a Gmail gadget, on mobile phones, and elsewhere into Google Calendar, both as a sidebar and a separate calendar.
Log into a Google Calendar account and you’ll notice a new “Tasks” list under the left-hand top links, which opens up the tasks sidebar that should be familiar to users of the Gmail Labs Tasks feature. It’s got the same basic indenting, deadline-setting, and basic sorting powers as the stand-alone and Gmail sidebar versions, which makes it a handy choice for those who live their digital lives inside Google’s primary information apps.
You can create a new date-specific task by clicking on an empty date in the Month or All Day views and switching the top link over to “Task.” Any task you set to particular deadline will show up in that day’s agenda, which somewhat completes the feedback loop. It’s still not quite a replacement for high-powered, contextually-driven to-do apps like Remember the Milk, but for the crowd that can get by just fine with simple text files or pens and paper, we have to imagine some basic email/calendar-integrated tasks are a fine little upgrade. For a full screenshot tour and detailed user tips, the Google Operating System blog is, as always, on the scene.
