In the latest update for smarty document manager we included a premium addon in the free version. Our very popular sub projects addon allows you to add nested folders and sub folders in a windows like folder structure, you can now enjoy this feature for free using our community version plugin. If you currently own the sub projects addon you can now deactivate it and remove it from your system. Updating to the latest version of the plugin will deactivate it for you autoatically!
