@NV has successfully converted ucnv’s Diff for Gist Greasemonkey script into a Chrome Extension, which can be accessed via the Chrome Web Store. The extension has been positively received since its release, evidenced by its continued use by early adopters. Additionally, @NV has developed another tool called github-live-preview, aimed at enhancing user experience by providing more UserScripts. The initial information and development updates were shared by Chris Wanstrath, known by his handle @defunkt.
