The goal is to support both the emacs usecase and the
usecase with fixed views for certain sets of files. The changes

between them.

Also make the 'x' in the toolbar close the document, and not the view.

This one has some magic inside to always use the current outputpane.
This solves the issue that I don't want Search and Build Issues list to
