Hi John, Actually, I looked into it a little further and it's not quite as simple as I thought. Here's the thing: When you use Control down arrow several times to bring the track height to mini, for example, the playlist button appears to be there but in actuality I'm not entirely sure that it is. If you try to click on it, it will not open. Now, if you close and reopen the session, the playlist selector will indeed be gone. Now, if you were to use Control-up arrow a few times to adjust the height back up to, say, medium, the playlist button does come back but it's not visible to VoiceOver until you close and reopen the session. Try it and see if it works for you.
HTH, Slau
