Do you think I should/could add this now, before KDE 3.2 is released?
How should the function look like?

KStatusBarLabel const *find(int id);

It says that KStatusBarLabel is an internal class... Maybe

QLabel *find (id);

Or with "Const"? The problem is that it is probably quite bug prone to
allow the user to play around with the Label instead of using the
KStatusBar functions... Or?

I would at least like to add some QASSERT or some debug message saying:

	Label-id already used.

Is this ok?
