I have been using some version of Tasks since 2003 and absolutely love it. Not only does it help me organize my thoughts and projects, it also provides me with a searchable database of all the solutions I have come up with for my projects.
For the last several months I have been using Tasks for all of my consulting projects so that I would have a record of what I did/what I needed to do and to have for my clients if there would be any billing disputes for hourly jobs. My clients can log in and see each task request, the task solution (with attachments and links if needed), and the time it took to complete the task at any time. Pretty slick.
Recently I realized that it would be very helpful to have a total time spent on a group of tasks so I would not have to manually count the minutes/hours…so I contacted Alex King and requsted this feature. To my surprise (especially after using tasks for three years now) the feature to calculate the time spent on sub tasks already exists. To see this calculation, all you need to do is click on the right most icon (Show Details) in the parent task. Rock on.
Thanks Alex for the awesome software and your prompt response!
