All of these could be fixed with a very simple approach that, when you:

• highlight a file in the file explorer list
• highlight a file in the Cmd+T or Cmd+P list
• highlight a file in the search results list

You will see a preview of the file in the editor window.

Some other notes:

• If you press enter or the right arrow on a file in the file explorer list, it will preview the file
• If you press enter on a file in quick open list, it will preview not open the file (NOTE: this may be controlled by the existing preview setting)
• But, if you press enter on a file in quick open list, it will open the file (not preview) (NOTE: no setting exists for this one?)
