But it's very important to be able to *move* tabs across windows or
panes.  For example, in XEmacs this is a somewhat frequent pattern for
me:

C-x C-f /some/long/path/foo.c                # edit foo.c
# work for a while ... oops, need to see what's up with foo.h
C-x C-f foo.h                                # look Ma, no path!
# want to see both simultaneously to work on several prototypes in succession
C-x 5 b foo.c                                # pull up foo.c in a new X
                                             # window, use mouse to position

That's quite painless.

In many apps, however, you would have to select the foo.c tab, close
it, bring up a new window, and open foo.c using the long path
(presumably with a file browser interface, but often enough the
default directory is wherever you started the editor, not most
recently used file).  Recent Files may help, but even there some apps
don't register a file with Recent Files unless it's been changed.

Since these considerations are somewhat subtle, I think it's worth
mentioning for your consideration.  Eg, it's *not* clear to me that
Recent Files should contain every file you've looked at, but if it
doesn't, it has the bad effect described above.  So if you're not
registering a file with recent files, there should be some other
shortcut way to move its display (eg, in a tab) across windows.

N.B. While I personally love Emacsen (so there, Nick Coghlan!), I
don't recommend modeling anything in IDLE on Emacs UIs, which were
designed by a guy with RSI who couldn't pay rent (until after he got
the MacArthur) let alone buy a 640x480-graphics-capable monitor. :-)
