I don’t read all the stories from a specific blog or a collection (folder) of blogs. I usually filter by the title of the post.
Having the initial view of all the stories come up as collapsed and expandable with a click on the subject (a la google reader) would be very helpful.
You might find the Preference “Show single story at a time” useful. Try turning that on and see if you like seeing only one story at a time. The story titles will still be in the bottom pane, but you won’t have the clutter of multiple stories.
Thanks for the idea. I tried it out and that works if I’m selecting a single blog to view but not for multiple blogs inside a folder.
