OK. I've been using PathFinder 8 for a few days now and while it does have something that looks and acts like Apple's Cover Flow, it is no replacement for Apple's Cover Flow. The Apple Cover Flow was smooth and fast. Sure, you could spin it so fast that thumbnails couldn't load in time. But scanning that fast would mean that your brain wouldn't have time to process what was scrolling by, anyway. At any reasonable scrolling speed, the images were loaded by the time they began to come into view. On the other hand, PathFinder's Cover Flow is slow and jerky. It doesn't load the thumbnails nearly as fast as the Apple Cover Flow did. Each time I take my fingers off the trackpad, to move to the other side and continue, starting up again is jerky and I often have to go back a few images, because it jumped forward at the beginning. A very minor issue that I just have to get used to, is that with Apple Cover Flow, I could also scroll with either the up and down or left and right arrows. In PathFinder it's only the up and down arrows. I'll get use to that.
Sure, PathFinder offers a substitute for Apple's Cover Flow, but a very poor one. At this point in time, I don't see myself paying the $40, when the free trial runs out. I'm now on the hunt for another app that may have a smoother and faster version of Cover Flow. I looked at PhotoMechanic and it may work for me. I'm not opposed to the $150, since I'll write it off, anyway. But at the same time, I don't want to waste that much money, if there is something that will do the job for half the price.
It would be so much better if Apple would just give users Cover Flow back in the Finder. I just can't imagine the thought process that led Apple to eliminate CoverFlow, in the first place. Well, I'm off to the Apple Feedback page again, to post yet another request for the return of Cover Flow. This is becoming a daily process.
