I had previously bought 1.x, which worked pretty good as I recall, but not great. Decided to try out the latest version. It is SO SLOW that it is essentially unusable. Basically, it takes a long time to load the library. Then, after it makes changes to some files (which isn't too slow) it takes FOREVER again for the software to give you back control. It feels like the program is resorting the list again or something. I highly recommend you stay away from this one. In the middle of writing this review, I started using Curator, which is really good, even though it is only 1.0. If a couple of features could be added to that, it will be the best.
