Bug tracker app

The title says it all. I think a separate, standalone app similar to the GitHub mobile app would be super useful, as it would make bug tracking a whole lot easier and more enjoyable. It would be directly linked to the current bug tracker, (obviously) just in mobile form.
Some new features might include:

• A notification system (maybe when you're watching a bug and someone comments, you get notified?)
• A better search function (whenever I search for bugs they never show up, even when I know they exist)

In conclusion, a mobile app version of the bug tracker would be super amazing.
