-+ View model design to show parts of data model in Qt widgets
++ Application model to store almost any type of data (independent from Qt)
 + Serialization of application models to json
 + Undo/redo based on command pattern
++ View model to show parts of data model in Qt widgets (Qt-dependent)
 + Some scientific graphics
 + Automatic generation of widgets from model content

 `SessionModel` has undo/redo,
