Fixed. I'm attaching a darcs patch and a screenshot of my IM
workspace. All the windows found
their placement automatically.

I don't know how to implement it this way, without any access to
Combo's internal state.
I could duplicate it's windows management logic and so maintain a
mirror of it's state, but I really
hate both high coupling and code duplication.

To my mind a better idea would be to explicitly specify all the
components invariants about
applying combinators, processing messages and stack management, like
requirement to
send ReleaseResources to all the sublayouts etc.
I had to spend quite a lot of time reading sources to get some bits of
knowledge about it
(esp. taking into account my modest Haskell experience).

Exactly. I've switched from Ion which always has black background and
immediately put
some fancy picture in the root window, that's why it was so noticeable to me.
I even thought that Ion does some kind of double buffering, but I've
just checked -
it doesn't, it's only a background colour which makes such a difference.

By the way, is it possible to implement this in WM: save old window
bitmaps and show them
instead of background image while windows are redrawing?

I meant reflection, I haven't even tried rotation. Reflecting a 1/3
division converts it to 2/3,
but dragging the splitter doesn't work anymore.

OK, I'll file a couple of reports.

Thank you.

 columns so that all windows on the screen are as close as possible to the
 desired aspect ratio.  As a side effect, the layout changes much more

[Merge emptyLayoutMod into redoLayout
Joachim Breitner <mail at joachim-breitner.de>**20081005190220
 This removes the emptyLayoutMod method from the LayoutModifier class, and
 change the Stack parameter to redoLayout to a Maybe Stack one. It also changes
 all affected code. This should should be a refactoring without any change in
 program behaviour.

Joachim Breitner <mail at joachim-breitner.de>**20080908105758
 This patch partially implements
 http://code.google.com/p/xmonad/issues/detail?id=215
 It adds a XPConfig option that, if enabled, hides the completion window
 until the user presses Tab once. Default behaviour is preserved.
 TODO: If Tab causes a unique completion, continue to hide the completion
 window.
