unlimited watched folders


I’ve only completed a couple of AS studio apps so bare with me here
So I have a stay open applescript droplet that users drop folder onto and the droplet will then watch for new items to be put in the folder. Hence when new items are dropped in the folder the script process them horray! if they quit the script it remembers the folder, this is also good. Only problems is there is no way for them to see what folders they have added. So here is where my question comes in (finally!) How can I get the same functionality only displaying the dropped folder path back in the UI ??
