Apparently some folks in the Gmail Help Discussion forum have come across a new Gmail feature: Task Lists. Just as it sounds, this would be a to-do list that resides presumably in your Gmail sidebar and would allow you to easily add and check off items as needed for a better way to get stuff done in your life.

Garett at Googling Google has dug into the Gmail code and found that there are in fact references to these “Tasks”, making it pretty likely these rumors are true. Also on its side is the fact that last October Google put a post up in the Google Calendar Help group that they were were listening to user feedback about wanting to-do lists and would “have more to talk about soon”.

As Garett notes, the ‘Remember the Milk‘ add-on does much of what this new feature would seemingly entail, but requires that you be using Firefox with GreaseMonkey – which I haven’t done in quite some time given how fast Camino and Safari run now compared with Firefox.

A To-Do or Task List that works in both Gmail and Google Calendar would be great. Better still would be if it worked across all Google applications such as Docs, Maps, and Blogger as well. Google is definitely getting better at integrating their services – moving closer to the vaunted ‘Web OS’ that is an on-again/off-again buzz word.
