Nokia :: Recently Used Numbers Shown At Start Of Contacts List?

I find that I call and message the same people more regularly than the rest of my phonebook. As such, I believe it would be much easier to have a "Favorites" or a "Recently Used" section at the start of my phonebook to quickly find my most commonly contacted friends.

The "Recently Used" section could be similar to how Microsoft Word works where it saves your last 10 used fonts at the top of the menu when you click to change the font of your text. How do I go about suggesting this to Nokia to update their software?
