Great work! Just one request which I haven't managed to find in any other app/site wrapper for HN... please highlight or otherwise mark new comments in a thread, or an ability to sort by 'new' like Reddit. It becomes too tedious and antiquated to scroll through the whole page every single time I want to read only fresh comments. I can't think why HN won't implement this, but it is a good opportunity for wrappers like yours to do so!
