I participated in a technical SQL forum at Tech-ED in Orlando this year that focused on Intellisense that Microsoft is developing for SQL.  We saw the current stage of their development and strongly encouraged them to get what they currently have stabilized and to include it in the release of SQL 2008.

We provided feedback on the features we would like to see and how  it is to operate.  Primarily we said that it should operate much like the Intellisense does in Visual Studio.
