You can add featured tracks to your Kompoz profile, to showcase your best work. To do so, begin by going to the track detail page. Under the track audio player you will see the green Kompoz icon in a button. Click that button to bring up the sharing dialog.
Next, add a comment in the sharing dialog that appears. You should keep the comment short, since this will appear on your profile. One or two sentances should be more than enough. Make sure you select the My Profile Showcase option.
