One of the features they pulled from 2005 is the Auto Complete feature.  This is helpful for someone who is new to a DB/Table, as well as improves the ability to quickly add items needed.

Would like to see one where the AutoComplete works across Databases and Servers.

Also, ability to easily go to a graphical view and back to scipt mode (think MS Access, or Enterprise Manager Views), but also smart enough to handle CASE and other statements that normally are not graphically displayed.

Able to create/learn your coding style, and apply to code (Formatting Script), this includes use of Tabs, how to structure SELECT statments, your Column List, etc.
