:-) With less than 50 lines of code, it showcases the implementation of
the policy that was formerly built-in in nitpicker. Since I moved this
policy to this external component, we can do anything we want by

It is exactly the direction I want to go. The externalized nit_focus
component was just a stepping stone.
Still, my remark about the nitpicker-focus handover between sessions
holds because such a mechanism is needed regardless of the layouter's /
nit_focus policy, e.g., for implementing dialogs with menus or sub-dialogs.
