This what we plan to do. However we must optionalise all of this via pluggable 
layout managers
as some insist on preserving the status quo.

How do you direct an event to a specific plugin, for example: now you are being 
shown onscreen
(for lazy-loading of backend data)?

This is what we had before and is completely useless.
Putting Richard's layout (or yours, there's basically the same) *inside* a 
notebook page makes the GUI unusably slow
to navigate and destroys the benefit of the sidebar.
