This tool itself isn't complex but I just wanted to shout out how easy it was to make my own section on the toolbar! Granted I did have to look at source code but when I did it was simple, clean and intuitive. Which in my experience editor UI in engines never is, so good job Facepunch Team!
Also, this made testing in general a lot easier, letting the fastest bot run and then simulating the average click time per target gave us a ballpark of how players might do time wise.
