Can you just leave it blank?
If you add this code as a In Line CSS resource the Queue title (and header space) will be completely removed.
.nx-queue { border-top: 0px; <br>}<br>.nx-queue-header {<br> display: none;<br>}
Now, this also removes the capability to filter or search on the contents of the queue. So reader be-ware…
Or, try this:
.nx-queue-titletext { display: none; }
You beat me to it. I was just coming back from Chrome tools to provide this CSS.
Shoot, I should have waited a minute more.
