If you know what files you're going to use in a particular service, you can put those files in your playlist so you don't have to search for them in your giant library.
To do this, when you hover over any file in your library you'll see a little star pop up. If you click that star, the file will instantly be added to your playlist.
If we click on the "Playlist" tab to the left of the Library, we can see other files that have been added. We can reorganize or remove files we no longer want in here.
Finally, once this service is done, we can hit "Clear playlist" to get ready for next week!
Playlist is super helpful for setting things up for volunteers and running Sidekick seamlessly.
