Thanks! I didn't even look under that button. When I was first setting things up, it showed me the icon and I figured that was good enough for me. Honestly though, I doubt even having looked I would have known what it did. I had to test today the difference between 'with text' and 'without text'.
Side note: I was testing out if it would work and didn't notice I had changed VLs to one that didn't have the test tag I wanted. Took a while to figure out why it wasn't working and was about to ask how to use it...
