Set the Scope of Apps in the App Gallery
You have an option for SharePoint farms to determine whether 'production' apps or 'development' apps are listed in the App Gallery when users publish apps to Web Part pages.
When users create apps in the MashZone NextGen Hub, they may not be completely finished or 'production-ready' for all users to work with. Once apps are complete, users publish apps to the MashZone NextGen AppDepot where they are reviewed and approved by an AppDepot administrator. Published apps are now 'production-ready' and available for other users to work with.
By default, the App Gallery shows SharePoint users all the apps from the MashZone NextGen Hub. This allows users to build or update Web Part pages based on newly developed apps. To ensure that users only see 'production-ready' apps in a SharePoint farm, you can instead limit the App Gallery to those apps which have been pulished in the AppDepot.
To control app visibility in the App Gallery for all sites in a SharePoint farm
1. Login as a farm administrator and navigate to Central Administration.
2. Click Application Management, then click Mashup Sites for SharePoint Site Settings in the MashZone NextGen Administration category.
3. Set either the List Apps from MashZone NextGen Hub or List Apps from AppDepot option to control which apps users can see and add to Web Part pages in sites for this farm.
