I have few bug and enhancement reports:

1. The vote up status seems to get reset or so it seems from the app. I had invited this post yesterday, by today the thumbs up icon color was black again. It looked as if I did not vote this thread. So I clicked on that, and then the thumb icon was green. Then I went back to the main page, and remembered to type the following point. So I came back to this thread and the thumb icon was black again. It looks as it the app is remembering if I have already voted for that thread. Does HN allow one to vote any article multiple times?

2. I like the concept of the navigation overlay. But can you please add an option to disable the vibrations each time that button is used? It gets pretty annoying after navigating few comments.
