Push this! This date-picking crap is annoying and no eye-candy...

fingerfriendly calendar showing up when clicking a date input field, similar looking or just the same like hildon-calendar-app in month view. Showing DOW & WOY.
Also the time picker, just the same! Make it an analog clock showing (for eye-candy) where you manipulate the pointers. A rolodex-looking alarmclock (you know what I mean? the old style without 7segment lights..)? A 7segment display where you manipulate the segments itself? Binary clock input?

these are just skins for a clock and date input, get it rolling
