A wishlist for my news Aggregator (currently Radio):
I want to be able to specify how long items stay in the aggregator on a per-feed basis. At the moment you configure this once and every feed gets that setting. Some feeds contain things that I know I have to think long and hard about, others contain ephemera that, if I don't comment straight away, I probably never will. Allow me to make that decision and make the aggregator more effective.
Allow me to combine feeds together into channels. Let me display & manage each channel independently. Let me use topic metadata to combine feeds dynamically into channels.
Allow me to filter posts and prioritize posts using topic metadata. Right now every feed and every post has equal priority, the only factor is "freshness". Let me specify key metadata that shows what I think is most important (a scoring system maybe?)
Give me a quick 1-click means of deleting all the posts in a view
