time spent to make a task
i don't if it's to complicate so much the system, but it would be great if we could write/note how much time we spent in some tasks. because if not, every task "has the same value" (in terms of time), and it's not "fair" to evaluate the time you spend doing some things (compared from others).
Thank you for your feedback, we appreciate it and we'll consider adding such option in the future. You're welcome to vote for this request in our Votebox: http://todoist.com/Vote/showProposal/259/
For now, as a workaround, you could try to plan the time spent on tasks by adding a label such as @1h or @5h - this would also allow you to search for tasks which require a certain amount of time to complete.
Thank you. It's really cool to feel that we (the users) could help you to rebuild Todoist's System (apart from my poor english).
