A k2 plugin that will allow an admin to choose standard K2 Extra field groups that would then be grouped in a row on a special tab in the K2 item.
Any number of rows can be created and each row can use a different K2 field group. The data would then be editable live in the row instead of entering an edit screen.
Some screenshots from a demo I'm preparing to show the features of Datasets for K2
