Good, but could use more

Ive been using the app for about a month now. I like it and have not had any technical issues, but I think it could use some more features. It would be nice if you could see on the main page when deals will expire, a way to categorize the offers available (e.g. Search by "thriller"), and a way to mark which offers youve taken advantage of as Ive noticed that they occasionally repeat. I would also like to see a way to mark offers youve looked at already; a "read" feature similar to what email programs offer after youve opened a new message.
Again, I like the app, and will continue to use it, but some enhancements would be nice.
