I want to add a field for tasks to note how long I think it will take. E.g., 2 hrs, 2 days, etc. Can I?
I'd be happy if I could create a custom field (i.e. like a custom column in Microsoft Project) to input this data. Is there such a thing in todoist?
although it's not possible to add a custom data field in Todoist right now (not counting task notes), you could use labels to add a "tag" to any tasks as a workaround. Simply type @2h within the task name and a "2h" label will show up next to the task name.
Still, thank you for your feedback, we appreciate it and will consider adding such feature in future development.
