I would love to be able to have a blacklist of terms that Feedreader would automatically mark as read. That or the ability within the filters to remove items containing a specific keywords.
For example, I am tired of articles on iPhones. I wish there was a way to mark all feeds with iPhones in the title or body of a feed as read. I have tried several different RSS programs looking for this feature.
Right now I am using the smartfeeds 'does not contain' filters along with the 'only in these feeds' features to kludge together all of the feeds I want while removing terms that bore me. I would be nice to be able to just be able to put feeds into a folder and then have the program worry above removing all of the garbage items.
