I like this, too. It feels like a Mac app. It asks you to select the app you want to add to your list and it imports as much info as it can. I couldn't figure out how to print (doesn't appear to have that capability yet) and I couldn't access the developer's website today in order to get the support email address.

It needs some additional fields such as purchase date, cost, etc., but I'll bet those can be added easily. It will be interesting to see how responsive this developer is.
