Will Remember the Milk ever track tasks and their duration say for an 8 hour work day? For instance, if i have 8 items on my list for the day (an 8 hour work day) and each item is one hour of duration, will this app ever track time available remaining? In my example if i were to add item #9....i would not have any room in my schedule to add a 9th item to my list. I was hoping for this feature because i tend to have a lot on my daily lists per day
