How could one move folders / files from the left panel or the binder to the right panel?

Here’s an example. Both editor panes are set up to use the Outliner view.

I’m moving doc “Creating a New Project” from the Binder to the left editor pane.

BEFORE

DURING - Drag “Creating a New Project” and drop it after “Bookmarks”

AFTER

I could have also dragged and dropped from editor pane to editor pane, or editor pane to binder.

Is this similar to what you are trying to do?

Best,
Jim
