Think about the Finder. You click on a file, get a preview. If you like it you can open it. That's what I'm driving at. You click on a row in a tableView, you get a preview (the opening is in code, I'm storing an index of file references in a different NSDocument) and if you like it you open up in a new window. The difference here is you can edit the file in preview.
I'll try your code. Thanks for the reply.
