Repetition of daily tasks would be key.
For those of us who struggle with day-to-day organization, it helps to have a plan in front of us every morning, afternoon, and evening. I would really appreciate the availability of having this right in front of me every morning. This would also allow me to track my time spent on these Important, non-urgent tasks.
It is a feature we have started working on, but the developer who worked on it left (he was a freelancer and found a permanent job). The work will start again at some point. It isn't an easy feature to implement.
