"Harry Brundage, a co-worker of mine at Shopify, does a lot of CoffeeScript development and said he would love to be able to do CoffeeScript right from the console in Chrome's Web Inspector. I asked Paul Irish, a "dev relations guy" at Google, to point me in the right direction on building just such a thing.

The result of today's pet project is CoffeeConsole, a Chrome extension that adds a new panel inside the Web Inspector. Type in any CoffeeScript and then hit the run button (or hit Command-Enter or Shift-Enter). The code will be compiled into JavaScript and then run in the context of the current window."

"Each extension panel and sidebar is displayed as a separate HTML page. All extension pages displayed in the Developer Tools window have access to all modules in chrome.devtools API, as well as to chrome.extension API. Other extension APIs are not available to the pages within Developer Tools window, but you may invoke them by sending a request to the background page of your extension, similarly to how it's done in the content scripts.
You can use the setOpenResourceHandler() method to install a callback function that handles user requests to open a resource (typically, a click on a resource link in the Developer Tools window). At most one of the installed handlers gets called; users can specify (using the Developer Tools Settings dialog) either the default behavior or an extension to handle resource open requests. If an extension calls setOpenResourceHandler() multiple times, only the last handler is retained."

"interface tweak that allows you to perform nearly any action or search by dragging any page element—a link, email address, image, or page itself—onto a transparent grid you set up. In other words, instead of right clicking an image to save it, you'd simply grab it and drag it onto the "Save Image" box that pops up when you start dragging. Similarly, highlight and drag text to search any of the search bar engines you've set up. Drag & DropZones' context offerings go a bit beyond what Firefox offers, and it's fully customizable in color, size, and transparency. Drag & DropZones is a free download, works wherever Firefox does." via lifehacker

Ubiquity's built-in command set consists of "user-centric mashups" that let you perform tasks using various web services in one place using natural language."
