If you have a list of media that is longer than the height of the browser window then the context menu (add, add & play, etc) is not fully visible. The cause is that the height of the main panel is sized to the content without the menu visible. For a quick fix:

1. SSH into pi
2. edit this file: /var/www/css/panels.css (needs to be done as sudo, and you may want to make a backup first).

.playlist, .database {
display: block;
——-> margin: 0 0 125px 0;<———--
padding: 0;
list-style: none;
counter-reset: item;
}

Basically, this just increases the height of the panel enough to allow to scroll down to access the full context menu. If someone is clever, you can change the height to accommodate the context menu dynamically. As well, you would need to scroll the context menu at the same time as the main panel. I just hacked it enough to stop my wife from asking me every time why she can't click the "play" button
