Well there is one ugly thing to note about the shrinkmaster and
growmaster proposal I did some days ago, which I heavily dislike
and that's why I also don't propose to keep them as an official
feature.

The problem is:

void
configurenotify(XEvent *e) {
        XConfigureEvent *ev = &e->xconfigure;

        if(ev->window == root && (ev->width != sw || ev->height != sh)) {
                sw = ev->width;
                sh = ev->height;
                setgeom(NULL);
        }
}

This event handler is invoked whenever X changes the screen
resolution dynamically. So for the case of
shrinkmaster/growmaster being the current geometry this means,
that the master area will shrink/grow whenever the
screen resolution is changed dynamically.

That's the reason why I propose to get over the idea of
shrink/growmaster.

Kind regards,
