There ought to be a simple way to move to the next and previous posts within a feed without closing the current one first. Other sites, e.g. Feedly, have arrows as illustrated. This should be a fairly simple change on the web code. I see something like this has been requested before.
What would be really great is keyboard shortcuts. This is common across various sites by Google, Facebook and others. On G+ and Gmail just hit the ? for a list. Standard keys are J for next and K for previous. We could have R to start a reply without having to scroll to the button and V for vote. Personally I find it easier to navigate like this with the keyboard than use a mouse, especially on a laptop touchpad. I think others would expect this functionality on a modern site.
What features would you put at the top of the list for usability?
