For adding we have: addToolView( "name", factory);
there's currently no API that can show/hide or delete a toolview
available to plugins. The uicontroller deletes the factory when its
deleted itself.

Until now no plugin knows about mainwindow's. A plugin that wants to
have a toolview provides a factory to create the widget that is to be
shown in the toolview and then tells the uicontroller to add a toolview
from that factory (with the given name). The uicontroller then decides
in which area to display the toolview (I think, Alex knows this better
as he designed the ui-library called sublime), however none of this is
implemented at the moment - AFAIK. The plugin doesn't need to know about
the mainwindow, there's no reason for this.

Thats fortune inserting a nice line at the end of my mails.
