I use it for 60 different RSS Craigslist search strings with my criteria. However, I'd like it to ignore DUPLICATE titles of feeds. I.E. if I didn't want to buy the item last week, I still dont want it this week. Automatically 'Mark it as read'.
How to do: write news feed title + date to text file . If feed title is same and date within arbitrary 30 days --> mark feed as read.

There must be similar examples of when duplicate feeds should be ignored.
