I couldn't find how to drag and drop components. I was expecting a "grid view" and then just to drag components from the left to the gridview and put them in cells.

I've actually had this same idea since grid is so flexible and the order of components don't matter for the container grid, so the structure of the HTML doesn't have to change by moving things around in a grid, just the CSS rules generated. Anyway good luck on launching the Beta version.
