Ah OK.
So, you just want an option to remove the Queue button that is beside the Song and Playlist buttons in ST4?
I know you've given a reason of "I don't use it" but is there any other reason? It's just a button after all. One could argue "don't press it" 🙂 Don't get me wrong, I'm all for a clean UI to minimise things you need to look at or click on (or avoid clicking on), especially if you are mid-live show. I'm also someone that never used the Queue in ST3, so I get it.
I only ask as based on previous conversation with Peter about the Queue vs Playlists, there were some changes in thinking going into ST4 about the importance of the Queue, and I suspect that is why the 'Hide Queue button' toggle didn't make it into ST4 (currently).
