This sounds a lot more complicated without much real gain. How about
just emulating syslog? Its a tried true way to do it, and it is
already widely understood and documented.
- messages post at log levels 0-7
- the menu item sets the "all levels up to X"
- the messages are tagged with level to be optionally colorized
If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess himself
of it. - Thomas Jefferson
