Feature: Move while in editing mode

While editing an item (ie double click in the list view opens a new window with just that item showing), it would be great if you could then move it easily. I can’t find any way to move it-- outside of the Classify window.

Maybe I’m misunderstanding what you mean but, here, Move To under the Action menu of the view window moves the selected item(s) if still open for editing. And while in a document window you can use Data > Reveal to select it in the view window.
