Always open file in new editor window?

I really want a double click on a file in the project window (or favorites window, etc) to always open the file in a new editor window, unless it is already open (then it should bring that window to the front). I've been using the Mac a long time and I'm used to each file being in its own window so I can see them all at once.

Is there a way I can set this up?

Thanks,

Howard
