Detail view appears very long on vertical screens


I am trying to editing Coda docs on my monitor that is placed vertically, which causes the Detail View appears as a very long block. I figured out that the Detail View adjusts it’s aspect ratio according to the window’s aspect ratio. But it does not work well when I want to edit on a vertical screen, which I like to use to view and edit docs. Could you tweak its behavior so it looks well in a vertical window?
