Refined Hacker News: Interface tweaks & features to make the HN experience better

Hello everyone, OP/developer here! There are many extensions out there that add quite a few features to Hacker News, but they also always do one thing, which I have realised, is a slippery slope: changing the minimalistic design and style of Hacker News. I created this extension with one thing in mind: I am NOT going to mess around with the overall design or style of Hacker News. It's sacrosanct. There are quite a few feature additions and interface tweaks that are implemented, a few of the important ones being: * Reply to a comment or edit/delete your comment without leaving the page (do it inline) * Navigate through items and comments using your keyboard (vim keybindings) * Sort/hide stories and auto-refresh periodically ...and many, many more. The GitHub README details all of them. The extension is available on both Chrome and Firefox. Hope you all enjoy it!
