Just so everyone knows, the 0.5 version is a little quirky under Leopard. It is very hard to get the settings just right because when you mouse over and click the slider bars start to migrate out of the window and the window can't be resized. It's very hit or miss requiring the program to be shut down and restarted to change the settings if you don't get them right the first time. It works, but is just exasperating to use. Earlier versions of OS X may not have this issue.
