These windows support multitasking features such as dragging, resizing, and split-screen combinations. 22 23Freeform windows are stacked on the Z-axis in the order they are opened or gain focus. When a freeform window is clicked or touched, it is brought to the front and gains focus. 24 25When a new freeform window is launched, it appears with a certain gap in the bottom-right corner of the previous window by default. 26 27Each freeform window includes a window title bar at the top by default. The title bar displays the application icon on the left and three control buttons on the right: maximize/restore, minimize, and close. The window title bar also supports [immersive configurations](https://developer.huawei.com/consumer/en/doc/best-practices/bpta-multi-device-window-immersive#section1477255312219). 28 29You can resize a freeform window by dragging its edges and move its position by dragging the title bar. 30 31 32 33**Device Support** 34 35- **2-in-1 devices**: Windows on 2-in-1 devices are freeform window by default. 36- **Tablets**: Some tablets support enabling [free windows](#free-windows) mode by pulling down Control Panel and tapping the **Free windows** button.
