To control a project’s visibility, go to Project Options and check the box for "Searchable subject galleries" to make it appear on your Studio Search Page. To hide the project, simply uncheck this box.
If you’d prefer not to use the Studio Search Page at all, you can simply rely on your platform’s built-in search tools. Snapizzi does the heavy lifting behind the scenes, but delivery and access are entirely up to your existing platform’s capabilities.
