I hope Cocoatech makes rapid improvements to PathFinder 8 as they did with PathFinder 7.
One thing: It is important to use a different folder in the Application Support folder to contain the preferences for PathFinder 7 and PathFinder 8. This way we can use both simultaneously. This is similar to how we can use multiple versions of Filemaker Pro simultaneously.
Currently, If I use PathFinder 8, it erases the customizations I did for PathFinder 7. this makes it very difficult to use PathFinder 8 with its current limitations.
