I have no access to the Beta but would love to know if this is still supported and whether any features have been added.
My wish list item would be better grid support for things like dragging/resizing column headings like Telerik grid.
I have to say I am learning MVC atm and am so annoyed at the amount of work I am going through with the whole entityframework/model/LINQ thing when I could do things with a web datawindow in no time.
