I wanted it to be a web app originally but it's not possible to do it in a nice way. For security reasons browsers don't allow to embed iframes to different domains or to even make AJAX requests to them.
Is there simply no way to login to HN for commenting from within the app?
EDIT: Eh, nevermind. I read a bit of the source and see more of what's happening. I'd thought this was simply fetching in and subtly styling the comments page directly.
I use this extension on Chrome, both marks new comments with a vertical orange stripe, and adds expand and collapse thread widgets, including one to collapse the whole thread you're in in the middle of: https://chrome.google.com/webstore/detail/hckr-news/mnlaodle...
Just to clarify: Do you mean there should be a refresh button for the comments view or should the app memorize what comments were already there the last time you viewed the page and highlight new comments?
