This suggestion could be combined with http://linqpad.uservoice.com/forums/18302-linqpad-feature-suggestions/suggestions/461315-show-sql-server-execution-plan
Use case: Press CTRL-L to translate the LINQ statement to SQL and display the SQL query + the estimated query execution plan from SQL server.
