I just tried your product and I absolutely love it. I like how snappy it feels and adding feeds of my own is a breeze. I also like how minimalist it is and I can just look at my feeds without some ads or content I don't care about bombarding me. With that being said, there are some things that could be done better:
1. Adding a new feed or (especially) removing a feed could be a little more intuitive. Now that I know how to use it it doesn't bother me so much.
2. An all expand in my articles would be nice.
3. if I refresh with the button in my articles everything is highlighted again.
If you don't care about doing more work in it I totally understand where you're coming from and things are fine the way they are.
