As an enhancement to [652324 - Code Generators for INSERTS/UPDATES]
there could be a feature, that if you wish to create Dummy data, you could generate the content or scripts to insert based on the datatype of the columns
The process could be
Right click on table name > Generate Dummy Data Scripts
(Ofcourse this could get messy if the table has more than one relationships, but that could be taken care of later on)
This could come in pretty handy, when the database is being created from scratch, and one has to create temp data by hand.
