Read top to bottom
In google reader, you could read articles (newest to oldest) using space. The benefit was that the content was always scrolling up.
In feedly, if I use the 'k' shortcut to read the next newest article and the article is too big to fit on the screen, I have to scroll down as I am working my way up the articles. Seems like an odd flow to me.
I'd like to see some kind of read with space functionality so I only have to hit one button to go through my new articles. If I hit space once I'm at the bottom of an article, it just loads the next one.
