I'll start off with article creation by defined users (original, eh?). For us noobs, a drag & drop layout designer would sure be nice. Paste images, text, previews and widgets where ever you like. That would give the ability to create a portal page or news page or nearly anything you want.
I picture it like this: create a box, insert content and be able to re-size it or move it where ever you want. That's the kind of flexibility I could go for.
