Please focus on the aspect that all these items (fonts, colours, icons) can
also be configured seperately.

What I would love to see is a theme mnanager truly honouring that. Theme-Cap
consists of Slick icons + FreeKDE.org scheme + Tahoma fonts, etc.

If a theme installs itself, it should not just update "current colour"
scheme but install the colour scheme it wants as a real colour scheme and
then select it.

Also, fonts/icons/colours/style should all use be tabs for one look&feel
entry sharing the same preview widget.

Yes, that'd be ideal.

Hm, check the current colour scheme preview for that, it already has that
seperation. Probably just checks whether you clicked the QWidget or QLabel
(text).

Hm, yah.. I guess.

Not with the current setup, no. It would be nice if KWin had a

static QPixmap *KWin::pixMap(QString caption, int w, int h, KStyle *style)

to make it easier to fake widgets. Preferably all widget effects should work
like this, having the rendering as a static member somewhere so any app can
use any effect whereever.

I'm doing the same for Quartz at the moment, I want to have those effects in
Atlantik in various places so I am making a QuartzEffect for KPixmap in
kdefx which will alow you to create a pixmap of any size for any colour
combo that will have Quartz effects.

My 2c.
