My old iMac running Snow Leopard died 2 days ago and with it the most effective RSS program that ran thru Apple Mail. I want something just that simple, but I can't seem to find anything similar. I've tried both Leaf and ReadKit, but neither let you read something and delete it from your feed while keeping the folder for the feed in the sidebar. The best I can see, you can just have it read or unread not deleted. At least if you can, I've missed it.
