I'm finding using this for farming the perfect CU is really nice. With the targeting on the left hand (ALT-F1 and ALT-F2) and mouse movement, it makes evaluation almost effortless. Every once in a while, the gump looses focus, and you have to manually click the eval gump to make it top-most again, but the script pauses while it's out of focus and will continue the evaluation. I still need to work on more safeguards when you are trying to evaluate under stress of being eaten by something. The classic client and EUO just don't do well with gumps. I really hope Cheffe fixes that in the new EUO.
Anyhow, this is a pretty useful tool.
