I don't think that sky would agree on this. We discussed last week the
centralization of the window management. A panel is yet another window type and
should also be able to be managed by this central manager. Since I am not
working on this, you should possibly quickly chat with mukai and or sky before
introducing the flag. I think that a more general "unmanaged" state would be
much better and could also be used for other cases.

I'm ok with this (reviewed this patch earlier on).
