Google developers have added a new flag named ‘Show Chromium App Launcher’ in the latest build of the Chromium browser.
This should soon roll out to Chrome Canary build and then on to the regular channels.
Enabling this option adds a new launch app on Windows OS’ task bar. You can see all the installed web apps through this launcher.
Google Chrome OS already uses a similar launcher for the web apps installed in the Chrome browser. Soon, you would be able to access them from your Windows Taskbar as well!
