I was trying to use ENS Asset from Construction category - The green EXIT sign with an arrow.. Unfortunately for me every single direction I needed was opposite way. I can not scale it (mirror it) cos it is a text. Like for example I can do with evacuation sign (running man).
So I think it would be good if the sign had on the back side as well the same text so I good rotate it if I need opposite direction. Now it is a simple white plate on the back. That would be easier than making another asset for another direction.
