Gospel.io provides many tools for you to get to grips with your entire resource library. Different attributes about your resources (like Topics, Author, Scripture, and Series entries) are called Groupings, and individual items in those groupings (A topic called 'Faithulness', an author called 'Bob Bobson').
From your Desk, you can access several different tools to help you sort and filter resources by these different groupings:
In the 'Resources' menu, you can select 'All Groupings' to view a list of all of your Resource Types (as of Gospel.io 1.0. you cannot add more Resource Types other than Sermons), Authors, Topics, Series, and Scriptures. 'All Groupings' is also where you would go to add or edit individual grouping terms.
You can also select 'Resources by [Grouping] to view a list of all resources that belong to a particular Grouping Term. For example, clicking 'Resources by Topic,' then 'Family,' will show you a listing of all resources that belong to the topic 'Family.'
From 'Resource Settings' you can also set a fallback image for Series' that don't have an image of their own.
