This is great. Thanks for creating it! Matches how I read comments, and fixes my only gripe with HN: I'm forever missing the touch target of the little [-] to collapse a thread once I have read it. Yes there is a next button too, but I prefer to collapse so I don't see what I've already read when scrolling around.

I found a bug on first launch. Every item was duplicated in the list. A refresh fixed it.

Anyway, thanks for building this, it's very nicely done and useful.
