Well first of all the interface is non-intuitive. For instance, a Select Folder... button would have been nice, and it wouldn't even allow me to tab between text input fields. First time I tried a search and replace it locked up on me. I force quit and relaunched, then the entire app came back at about 5% opacity (or 95% transparency)...weird. I thank the author for trying but this app definitely needs some work. I use Panther 10.3.2.
