The tray has _also_ different semantics from the taskbar. Because it has all
kinds of semantics. Your definition of the tray may be the best one I've seen
so far, but it's still not a very good one. How is an application hidden in
the tray a service? I don't consider KSIRC, KMail, K3b or Kaffeine to be a
service (and depending on how vague you want to be with "service" Noatun,
KSCD, Amarok, Juk, Kopete etc. are not services either).
I am aware of the fact that the tray is not the taskbar but a mess of things
even the person who maintains it cannot define. That's why I want to change

All apps can use it with my patches.

You can already now ask for application status (the demands attention flag),
and I can add easily add more, just say what you want.

Hmm. I see I'll have to create patches also for 2),3),4) from my proposal so
that I can present it in a complete form.
