Deadlines: Change indicator to days left, e.g. "3 days"

Deadlines are very useful for me, it's the standard sorting in my Inbox. Although I would prefer to see the days left, instead of the date in the bottom right indicator. It would give a better overview which tasks are urgent.
Examples: 3 days, Today, -1 day (red)
If some users prefer the date, it could be a switch in the settings.
