Live query results
I often use LINQPad to check for new or updated data in SQL tables. I have queries open that I refresh after I make an operation in my application.
It would be really helpful if you could create "live" queries or a change log for a database table or query. I think it would be possible using SqlDependency to get the required notifications.
I imagine something like new or updated rows are added to the bottom of the searchresult and the search result is scrolled down. New and added rows as colored for a period of time to visually indicate that they are updated.
