Hmm.

At that point, one could argue that you still have the capture open, in some sense, even if you don't have a viewer window for it.

I'm not sure whether any other applications support the notion of a main window for a file, windows for stuff from that file, and closing the main window and leaving the other windows open, so I'm not sure what UI models there are for us to follow when providing this capability.

Apple Mail lets me double-click on a message to pop up a window containing it (an analogy to double-clicking on a packet) and then close viewer windows (analogous to the Wireshark main window for a file) without the individual-message windows closing - but it doesn't have the notion of mailboxes as documents.  "New Viewer Window" just pops open a new window for all my mail, with a pane to let me browse through mailboxes and view individual mailboxes.
