Google is about to give Android tablets a serious productivity upgrade with a new feature that could change how we use these devices. Google's testing a new feature that lets you resize and arrange app windows just like on a desktop computer.

Google is testing “windowing” for Android OS while it is used on tablets. It could allow Android tablets to function as desktop PCs.

Google is testing a new feature for Android tablets that will let you resize apps freely and arrange them on your screen at will, making it easier to juggle multiple tasks. The “desktop windowing” feature is now available as a developer preview, and for apps that support it, you could even have more than one instance open.

Soon you may be able to use Google’s Android operating system more like a desktop operating system… at least on tablets or other devices with large screens.

The Developer Preview for Desktop Windowing allows the flexible arrangement of app windows on Android tablets, similar to a desktop PC.

Google is adding a new window tiling feature to Android tablets with an Android Open Source Project (AOSP) update. It will improve multitasking and integrate Android tablets better with keyboards and mice.
