The importer will organize Photoshop content according to special naming conventions that have been assigned and place items within the Application Model accordingly. Important Naming Conventions:
Photoshop group folders named with _layer at the end will import to Storyboard as a layer. Content within these group folders will import as project elements within that layer such as groups and controls. All Storyboard groups and controls can not exist outside of a Storyboard Layer.
Photoshop group folders named with _group at the end will import to Storyboard as a group. Any content within these groups will import as controls within that group.
Photoshop groups folders named with _control at the end will import to Storyboard as a control. Content within these groups will import as text or image render extensions of that control.
Naming a PSD layer ending with _up directly above another layer with the same name ending with _down will create a control that behaves as a button. The control will be assigned events and actions and given an image variable that will work as an interactive button control upon import to Storyboard.
