When the plugin is configured (choice of a project via the plugin menu), a new menu appears, based on all the layers that contain the original project.
Tip : a separator can be configured by creating (in the original project) a layer group named "-"
Attention : the project must be configured to record absolute paths
The project might be stored in a PostgreSQL database. You need to copy/paste the project path (Project properties -> General) into the field.
Option of the plugin "Load all layers item" if it is checked load all the layers of the same level submenu
"Create group" option put the new layer in a group with the name of the parent level menu (v 1.9)
You can hide the administration dialog of the plugin by adding a menu_from_project/is_setup_visible to false in the QGIS INI file. This is useful when you deploy QGIS within an organization.
