The Manage Story Templates menu allows you to view all of your Workspace’s Templates in one place.
There are two ways to get to the Manage Story Templates menu. You can get there by opening the Create Story from Template menu (found by hovering over the right-pointing arrow in the Create Story dropdown menu) and then click on the Manage Templates button. Or you can get there by going to Settings > Workspace Features > Story Templates.
Here you can see who created each Template, when it was created, as well as rename, edit, and delete a Template.
