Alternative launchers have been on Android since the beginning, and most of them have made their name by taking the stock experience and piling on new features. Action Launcher is a little different. This app shakes up the UI conventions of the Android home screen, and it's really got some good ideas. The new update fixes a few niggling issues with the way apps and widgets are added to the home screen.
Adding new app shortcuts or widgets to Action Launcher before this update was perhaps the most clunky part of the experience. You'd have to open the customization menu and scroll through the list to find the items you wanted.
