Notication Center PLEASE :)

I love my Android I do but can we get a Notification Center with Widgets? I mean like having a calendar or use-able calculator, live weather widget, running tickers, music player...anything!! I hate the iPhone but there's somethings they have just done well. Is there anyway of getting some Dev's to give it a shot? Or does anyone know of any existing apps I have searched all over
Thanksgiving so much!!!

Which ROMs do center screen Knock Off?

Like the title says. Is this even a function of the ROM or something else? I'd like to double tap the home screen instead of the status bar to turn the screen off.
