When you start Neat Image, the Filtration Queue window
is opened (if it is not, uncheck the Auto create new job at
startup setting in Neat Image Options).
This window contains the filtration queue itself (in the left box), a set of
tools to create, edit, delete, start and stop jobs (on the toolbar), and the
panel on the right with detailed information about the queue as a whole and
about any single selected image filtration job.
