I always find myself jumping between EM and query analyzer trying to get information on what datatype I used for a particular db column (actually now I just open up the treeview in QA but that was before I discovered that hehe).
Anyhow, its something to checkout and it is a very useful tool especially when building stored procedures and the like.
