  I dug a bit more into this, and it seems that the new IB 3 doesn't
have this feature anymore. This is a general complaint about it that
I've encountered on several forums. This is because IB3 can synchronize
with XCode automatically so you're not supposed to subclass manually
anymore... unless when you're not using XCode dammit !

Some people answer that it is not a problem because you can now also
type in any class name whatsoever; even ones that are not known to IB.
This is true, but still a pain, because when IB knows about subclassing,
it is able to present you with interesting outlets and actions directly,
which doesn't work with an unknown class :-(
