Improving the feed reader

I keep a list of ideas for improving the feed reader. Not that I have any plans to build one, it's just something I like to do. You never know when an idea like that becomes usefull.

Anyways, I spoke with Casey about readers today and mentioned my memory of one (in development) that displayed a small thumbnail in one of its three panes. This, in theory, gives a quick view of the overall presentation of the blog. Pretty nifty.

How else can the reader be improved I wonder?
