As a mod, I guess this is embarrassing, but I've been aware of that little red button for a long while - but all I thought it did was make the banner bigger! 

Ah, well, at least I'm honest, I guess 

At least being Red it is visible. A bit of a nightmare when it was white.

Never noticed the red button before.  Doesn't seem to do anything particularly useful tbh.
