So I've been mapmaking for over a year now, and have worked for over 150 hours on maps. But then the other day while I was working on a map I for some reason looked at the magnifier tool and I realized I had never really used it ever. I think I used it once when I first tried to use hammer and was just pressing buttons. I really do not understand how I have managed to pass over that button for so long without even realizing it was there. So what I wanted to know is if anyone actually uses this frequently and if it has any helpful uses.
