This needs some work. It works, but not like I would like.
First, for a mere $6, you can eliminate the long delay at launch.
Then you see the contents of your home folder. It is not obvious how to navigate. doubleclicking a directory does nothing. There is a button to change the default directory, but I would expect that to be a menu item or a preference. In the menu, you choose a directory to list. Drag and drop would be more logical, or at least a button for this most important function.
What I would prefer is a contextual menu item for printing the directory.
