Block End Users from Browsing Public App store
Currently there is an option in Central Admin to disable access to the public SharePoint store to get Apps. However when this is enabled, it still allows end users to browse the public store, but it just blocks them from downloading Apps/Add-Ins. It will instead add their requests to the App Requests list in the App Catalog. It would be nice to completely block and disallow access to the public SharePoint store.

This capability is absolutely needed. For enterprises looking to manage what can or can not be done, the only option of forcing users to request apps is inadequate. We should have ability to choose whether the store is available to browse.
