  The Workbench 'Shelf' offers the user the possibility for storing subsystems for later use.
  Different categories and sub-categories can be created and subsystems can be added from 
  the current pipeline to the shelf. The subsystems in the shelf can then be added to other
  pipelines at a later time. The shelf is persistent across restarts of the workbench.
</p>
<p>
  It is also possible to export shelf categories to disk and then import them again. This offers
  the possibility to exchange shelf categories containing pre-built subsystems.
