For editablefields, you need to make a new View that is of the editable type. Once this becomes stable, I want to make it a default page in Übercart, but you have to do it manually for now. As you're building the editable View, add fields and make them editable as well. Continue with filters and sorts as necessary.

When you view the View, it becomes a form that updates all of the nodes that are visible on the page.
