The more content you collect in your MEDIA, the harder it can be to keep track of them all. But with the search function and the filters you have a clear overview!
The search function allows you to search specifically for titles or to display only content that have the entered word in the title or in the description. With the categories next to it, you can limit the search to certain (sub-) categories.
Clicking on "Name", "Duration", "Views" or "Added" allows you to sort the displayed content by title, length, number of clicks and upload date of the videos in ascending or descending order.
