It would need support for meta elements to define tasks in the jump list, and the JavaScript API for defining Jump List categories, icon overlays, etc. These are detailed here: http://msdn.microsoft.com/en-us/library/gg131029(VS.85).aspx Reproducible: Always Steps to Reproduce: 1. Open a website with Pinned Site support 2. Drag the Favicon to the Windows 7 Taskbar Actual Results: No custom Jump Lists or Pinned Sites are created. Expected Results: It should pin a site to the taskbar with the icon specified by the <meta> tag, give it a custom jump list specified by <meta> tags, and interact with the website via the JavaScript API.
