I'm coming from RSSOwl and there's only one thing holding me back. It is too time consuming to click on each item on the news item list to see them on the browser area. I want to click on the folder/feed and see all of its contents on the browser one after the other. Then I can just scroll.
I found a picture of how RSSOwl does it: http://img.brothersoft.com/screenshots/softimage/r/rssowl-24766-12596366...
Hopefully you will consider this feature. And sorry it you can already do this (I tried and tried but couldn't find a way).
