Query: Milwaukee 8977 heat gun

Great heat gun. Works really well, and relatively quiet. Light enough you can use it for a long time without fatigue. Like others, I wish there were some markings on the back, so you could choose a setting - even if it's not a temperature, a relative setting would be useful. A Sharpie pen will do the trick, but it seems like Milwaukee should add this feature.
