This section introduces the home-screen of Wolfgang. There are two types of home-
screens, depending on the selected net type. They dier in the layout of the toolbar
and the properties for checking the net. However, the dierences are only relevant when
it comes to editing the nets, which is shown in the next chapter. The following gure
visualises the home-screen for a P/T-Net.

The core of Wolfgang is located in the middle of the screen, where nets can be edited.
The right section shows the graph properties and work ow-specic net properties which
both are aected when adding elements to the net. These elements are going to be
discussed in section Editing Nets.
