Agreed. Extra functionality can be built on top of what is there
already. Adding categories, etc, via overloads is fine, IMO. Things
like file logging, socket logging, etc... need a bit more
consideration, but are also not something that is unthinkable to have
done as extensions of the existing system, which also handily provides
log *levels*, even if not categories. (think: qDebug(SOCKETS) <<
"Socket created"; .... qWarning(SOCKETS) << "Couldn't connect, did
something break?"; type things)

Something related I'd like to stress here (not to anyone in
particular): when you write this stuff in applications, it can be
changed at will. But when it's in Qt, you can't change it for a very,
very, very long time (if ever) if you suddenly decide the
implementation isn't ideal or you could do better. It's better to not
jam the moon on a stick into it from the word go, to take some time,
and do it properly.

My point is: feature requests are great, I'm sure we'd all adore them,
but let's rush into implementing without considering them carefully :)
