Estimated time on tasks

it really motivates me when i see small tasks with the estimated duration they'll take. For the tasks that are not planned on the calendar at a specific date, it'd be nice if we could add a "15m" for example in a "pay rent" or "send email" or "take trash out", like this i won't postpone it because it's just 15m and i won't delay it to the following day.

also for the future, besides this on unplanned tasks for today but without a due time, it'd be nice if all tasks had this estimated time. and when we planned them on the calendar, that it was this estimated time, but with the timer/pomodoro feature that is under review right now, since that would be developed already, when we do a pomodoro for a specific task that is planned on the calendar for 3pm-4pm, and if we end it within 1 pomodoro of 45 mins, it automatically shortens the task and makes it appear 3pm-3:45pm on the calendar, showing the new reality and that we have spare time :) useful for work!
