SQL Buddy - Query Analyzer with Intellisense
The guys that are developing this said they welcome criticism and suggestions, so fire away if you have any. My dream feature - save all open query windows to a temp file. I hate rebooting with 12 open windows in QA... Seems like they could be easily dumped into a temp XML file with the connection and SQL text.
Hopefully Yukon will give us this kind of fun built into VS.
