Welcome to Media Library! This area is designed to give you another way to access your media.
All of the content that is stored within your categories, are sorted here according to the type of media it is. You will see from the screenshot below how this is arranged with a variety of sections (these sections will depend on the types of media that your app holds).
Once you push into a media type, the content will only show the media of the file type you have chosen. When you find your desired piece of media, you are able to execute the same functions, by pushing the '+' sign in the top corner, as you would when finding it through the category level.
