Rikkus: please document! (Matthias)
Ok, here's the docs :)
You call delayedShow() instead of show() directly.
If the 'ShowDelay' setting is false, show() is simply called.
Otherwise, we start a timer for the delay given in the settings and only
do a show() when it times out.
This means that you can alt-tab between windows and you don't see the
tab box immediately. Not only does this make alt-tabbing faster, it gives
less 'flicker' to the eyes. You don't need to see the tab box if you're
just quickly switching between 2 or 3 windows. It seems to work quite
nicely.
