I've recently started playing with iCal after having a go with Google Calendar. One thing that's really bugging me: in the to-do list is there any way to indent tasks as one can do in Google Calendar? For example, can I create a task 'Finish article' assigned to a calendar 'Work', but then have indented sub tasks underneath, for example 'Do interviews', 'Plan out article', 'Check spelling' etc? Is this possible? If not I may give iCal a miss to be honest. Thinking about alternatives. Any other suggestions for free apps that combine calendar with a good to-do function would be useful. Thanks.
