I saw this article that seemed interesting, then for lack of attention I lost it... I wanted to go back and read it but it was very difficult to find it--not 2min. had passed!

It'd be great to be able to search for the stuff that I'm supposed to have read or are part of my selection.

The search on top is very strange, behaves impredictable! You should at least make it display the results from your feeds preferences (it currently searches for sites and whatnot).
