Introducing
Chrome Web Store Development Mouse Gestures
for Gmail there are 46,710 applications in Chrome Web Store tones of games, mostly embedding flash contents there are some exceptions (HTML5 power!) only free applications! potential business models: In-App Payments I separeted those apps into two groups:
games & tools http://www.google.com/wallet/business Google Account
Developer registration fee (5$/year) Gettings started Context Menu Desktop Notifications Omnibox Options Override Pages bookmarks, history, newtab Page Action Browser Action Google Wallet or custom payment (like PayPal) FYI: You can set the icon in two ways: using a static image or using the HTML5 canvas element. Using static images is easier for simple applications, but you can create more dynamic UIs — such as smooth animation — using the canvas element.

(app details, permissions, version number, external files, etc.) Tools: extension that integrates directly into webpage or extend functions.

Content Script Content scripts are JavaScript files that run in the context of web pages. By using the standard Document Object Model (DOM), they can read details of the web pages the browser visits, or make changes to them. A common need for extensions is to have a single long-running script to manage some task or state. contentscript.js Application details & define "Page Action" manifest.json background.js The manifest Megvalósítás What is it?
