In dired.el, near the top of a loong initialisation of the dired keymap
(line 1191), there's a line like this:

(define-key map [mouse-2] 'dired-mouse-find-file-other-window)

Looking at the definition of dired-mouse-find-file-other-window, you
find:

b.el
Description: application/emacs-lisp

(yes. Eek) So I would try something like the following:

c.el
Description: application/emacs-lisp

Note that this is a bit rubbish - the only change is on the 3rd last
line of the function. If anyone knows whether it's possible to
dynamically bind dired-other-window to be dired for a sec while calling
the other version, it'd be a lot more elegant.

Anyway, that worked for me here!

Well this one's easy :)

C-x 0 deletes a window, so if you have the situation you described, when
you're in the window marked *

/-------------\
|  *   |      |
+-------------+
|      |      |
\-------------/

hitting C-x 0 will give you

/-------------\
|      *      |
+-------------+
|      |      |
\-------------/

etc.

I didn't know of existing code to do this, so I hacked something up
myself:

a.el
Description: application/emacs-lisp

Exercise for reader: Deal with the rounding errors that I've completely
ignored.

That said, it seems to work reasonably well here!
