Better than Paper

Frustrated with my paper list which is covered with check marks and revisions, I went looking for an app to track my Christmas cards. This one does what I want.
However, there are no instructions or options available. Once you figure out how to import names (not that difficult) you have to figure out what the 2 available symbols mean. The left side features Check marks in Santa Hats and the right side features envelope icons. I figured out that the check marks were for cards sent, and the envelopes meant cards received.
I would like to be able to modify the background graphic. The bright red mailbox obscures part of your list.
For a paid app, there are no bells or whistles and I can understand those who feel it should be a free app. I have a lot of paid apps that I hardly, if ever, use. This one will be used annually.
