Hey, thanks so much for this app, I love it!

If you could, I'd like to suggest the following features:

• I'd be great if clicking on comment links actually launched the browser.
  
• I think it would be amazing if the kinetic scrolling could be modified to always stop at the top of a comment. It would make getting through threads and long comments much easier. Similarly, it'd be really handy if hitting the up or down keys on the keyboard scrolled up or down exactly one comment.
  
• It's a bit hard to follow threads due to the tiny (2 pixel?) indentations. Maybe a thicker line to separate threads, or if you want to be really fancy, a double line to separate thread branches and a triple one to separate threads?
  
• As previously mentioned, an option to display the top submissions would be great, as would the option to sort comments by top, best, etc.

Thanks again!
