Thanks for the positive feedback.
We are very aware of the current limitations of the Feed section and we definitely have plans to address the areas you have suggested. We are going to wrapping of the feed so you don't need to scroll the the right, make the URI's active, and add the ability to reply/retweet/comment etc to the feed. We are also going to see if we can merge together the various streams/feeds from your different networks. We actually have a new release scheduled for this afternoon with a few other features added but I would hope we can add the above features in the next week or two.
