I know. It was an alternative idea.

`message' is used for ephemeral info, very ephemeral (just a keypress
makes it go away). I was thinking about something stable that is hidden
(totally or partially) while the minibuffer/echo area is used for its
current purpose. But your comment about `message' makes me think that
*maybe* it would be confusing/distracting/etc when something is posted
to the echo area with `message' to be quickly replaced by the global
info. It may create a blinking effect.

I don't like standalone frames for things like the minibuffer or our
hypothetical global info display. I work on just one frame and reusing
the minibuffer area looks like a good idea, if it could be implemented
on a sane way. If that is not possible or convenient, a dedicated line
on each frame looks like the next choice.

(If the global info line is displayed on just one frame, what happens
when the user creates a new frame on a remote display?)
