I would like to present HackIt! - a Hacker News client that I've built for Windows Phone 8/8.1. It was just approved and published to the store last night: http://www.windowsphone.com/en-us/store/app/hackit/f96b7128-974d-4cba-8c43-41461865a0f2

While the app doesn't support all features from Hacker News yet, I would like to continue working on it and improve them, hopefully, with some feedback from users on what they would like to see in this app.

The app contains at the moment:

- Listing of News/New/Ask HN items

- "Infinite scroll" type of loading

- Viewing posts and clean in-post navigation.

- Viewing comments

- Log In functionality

- Account view and submissions

- Post and comment upvoting, downvoting, sharing and mailing

- Replying to comments and placing post comments.

There are also a few things that I am planning to improve/add shortly:

- Support for Windows Phone 7

- I am not sure if post/comment down voting works at the moment because my account doesn't have enough karma for it :)

- Account comments

- Support for multiple accounts

- Live tile with account notifications

- Some improvements in the user experience and design (at the moment, comment actions such as upvoting do not give any feedback to the user)

The trial version contains all "Read" functionality and I've added a paid version (USD 1.49) which includes all account interactions.

Please add some comments/feedback/criticism. If you download the app I look forward to any feedback on your experience.
