item moving automatically to #next at a given date

Hey there,

I think it would be good to have a special stack, that would include dated items that would, at a set time, move up to the In Tray column (or anywhere really). 

This would be useful for deadlines - I don't always want to remember that I need to prepare an abstract, but a reminder about a week before would be good :)

In the meantime - thanks for everything else!

Si
