The windows feature to estimate how long a task would take so as to be able to plan better, or to go: I have half an hour left, what could i do in that time? would be really awesome. I'd very much like to be able add a time estimation while adding tasks with a hokey like the @ for context etc.

Example:
Do the dishes @Home ^Today #CleanHouse &Private %15 (adds the task with a 15 minute estimation.

Kind regards,
