A new release of my SSMS add-in is available at CodePlex.
It adds 3 new menu items to the Table context menu in Object Explorer:
"Show Table Data" (Edit table data in DataGridView)
"Import" (Import of CSV file - generates INSERT statements)
"Rename" (table name only)
Please try it out, and provide any feedback here.
In addition, I have updated the project documentation.
