Bring Web 2.0 functionality to due dates in GoPlan

I'd love to see an easier way to deal with due dates in GoPlan. I've used several apps like basecamp, highrise, batchbook, zoho projects, google calendar, etc. and they all have a really easy way of assigning dates to things.

GoPlan uses the drop downs for month and day, but on these other systems, you can type in a date without having to work with cumbersome drop down menus. More importantly, you can use natural language words and phrases such as today, tomorrow, next Friday, next week, or next month. If you've ever used google calendar you know what I'm talking about. It assigns the due date based on the natural language logic. Well, I've gotten spoiled by working with due dates in this manner. It's really slick and I really hate going back to drop downs. Granted it's not a deal killer and actually a pretty minor thing, but since we're encouraged to share ideas and ask for stuff...

I think it would be great to have that capability in GoPlan!
