Performula has been built with flexibility in mind. You may have bought a new material, and when you search for it, it turns out you haven't added it to your library yet. Don't worry, just create a new item by using one of the methods listed in the previous section about creating items (for example pressing the always visible yellow + button on the top right corner of your screen), and navigate back. Then, select the newly created item which will automatically appear in the browsing list.
