At the 20:34 minute point in the video, Mark has the cursor on a DataGrid, and it shows some items in the Property Grid called "Generate Columns", "Remove Columns", and "Edit Property-Bound Columns". I thought "Cool, you can now generate columns later
on in the development cycle" (after that first drag and drop manuever).
But I downloaded the latest bits, and I don't have those same options in the Property Grid. What's up? Is this a feature that didn't make it into the Release bits?
