I'm not sure what you mean by "opening the note in a split". My desired behaviour would be, where you have an editor pane on the left and a preview pane on the right, clicking a link in the preview pane opened the note in the editor in the left pane and updated the preview accordingly. So the preview pane behaves like a web browser, and the editor pane follows whatever it is diplaying, just as changing the editor pane changes what is being previewed. I'm not sure I expressed that very well.
