Task Due Date - Availability Indicator
It would be helpful if there were some way to indicate on the drop down calendar selection tool for due dates, that there is limited or no availability on certain dates to complete tasks; this designation could accommodate extended meetings, all day events, Vacations, etc. I picture the date shaded by color or encompassed by a shape. This would allow users to avoid putting tasks on days that they will be out of the office or unavailable. Maybe a simple calendar module that lets the user block out dates with a selected level of unavailability (Busy, Half-Day, Out of the Office) and a place for a short note that will pop up when you hover over the designated date in the due date selection window, inside the task window.
