With large screen size such as the 10.1 2014 and 12.2, I would like to run applications side by side. For example, one two pdf files, a web browser, etc. So far, I have only seen applications windows being put next to each other (i.e. the screen is divided into 2-4 areas each running a separate applications). Is it possible to make them stack on top of each other likes what we do in Windows and Mac OS? That way, each application can be run on a larger window.
