It would be useful to see a date / time when a task was added / created. is that possible or planned for a future release.
Unfortunately, it's not possible to see the date a task was added right now, but we will consider adding such option in the future. You're welcome to vote for this request in our Votebox: http://todoist.com/Vote/showProposal/646/
For now, as a workaround, you could add a note to a task and you will see the timestamp showing when the note was added.
Good Tip David, I will use that, however it's long winded to be forced to create a date stamp by having to add a note.
