Z+ UI - A Decision

I have made a decision with respect to the layout of the Z+ UI.

This the variant that was suggested me in an email, and I agree. I however now think that a permanent message area is overkill, and will probably make messages appear for only a few seconds (with a possible scrollback).

It’s not worth thinking any further about this until I get some basic implementation going. I think the next thing worth looking at is the file format.
