If opening Google Chrome's new tab page just to fire up an app feels a bit too clunky for your liking, check out a new extension from Google itself: App Launcher.
Once installed, you'll have access to a drop down menu which lists all your apps in alphabetical order -- unlike previously reviewed AppJump Launcher, which doesn't appear to list them in any particular order. Google's offering also features built-in search -- which could be handy if you've been able to find a whole pile of apps you decided to keep installed. Keyboard navigation is supported as well, allowing you to arrow up and down and tap enter to launch.
The extension currently lacks an options screen -- which would be a great place for Google to slap in another missing feature: hotkey support.
