Each Joe in the collection has a thumbnail, the name, the description, and a place for you to add your notes and whether or not you have it in your collection.
Filter on the year that you're looking for, whether you have it not, and search across the Joes and your notes. There's a grid view to see multiple items at once.

The Pro version removes the small banner ads (you might see them the first time). The Pro version also can export to a spreadsheet, letting you share what you've done on your phone.
