Windows 7 taskbar is already popular with its features which includes pinning and jumplist capabilities. You can pin any app to the Windows 7 taskbar, but with Pokki, a new freeware tool, you can pin webapps to Windows 7 taskbar. There are various web apps included or available in Pokki and these run on top of Pokki. It is designed using HTML5 and allows you to access these web apps easily from the taskbar.
Currently there are only few apps available under Pokki, which includes Gmail, Facebook, Twitter App, eBay and few other sites. You can easily access these services from the taskbar in a beautiful interface.
Once installed, they appear as icons on the taskbar and pops out when you click them, enabling easy access. If you are a web developer, you can also create a Pokki app using the API and add it to the list once it is approved.
Pokki looks very promising from the initial stage itself, if they can bring in more app it would be one of the best apps to access all web apps in one place.
