With this enhancement, you can package referenced/dependent objects at the time of creating a cab file.
For example, for a selected Dashboard object, you can build a cab using all the objects associated to that dashboard by clicking the "Include Dependent Objects" checkbox. iPackager will automatically build all objects related to the selected dashboard.
In the below image, you can see the dependent objects like Query Objects, Cube Objects, Reports and Dashboard Widgets required to build the dashboard.
