Used this tool for a log time.
Still useful, but... If you own a modern Intel Mac you will notice this app is coded from the distant past...

- Very dated cluttered interface a'la OS 4,5,6,7 etc

- Even with the new Intel builds the app acts as if it is strictly single threaded & running as a carbon app not a responsive multithreaded cocoa app. If you use it for heavy work you will notice it bog down

Nice tool but really showing its age now.
