To add a simple to do list to gmail, create a [ ToDo] label and tag and archive messages requiring followup tasks. If you prefer to keep your list of labels minimized, you may create a Quick Link for the [ ToDo] lookup to see your [ ToDo] list. When you complete a task, don't forget to remove the [ To Do] tag from the message.
