The ability to publish one or more selected posts on other websites without resorting to 3rd-party RSS software, publishing that will correctly display UBB codes.
An "Unsubscribe from email" link in every automated email that will work without forcing the user to login.
User blogs confined to a defined area (revokable permissions by groups).
The ability to switch off "Magic URLS" in the control panel (I currently hack the code to stop auto-conversion of text to clickable URLs at this time)
A wider selection of professional-looking CSS stylesheets/themes that comes packaged with the product.
