With the Modern Windows 8 UI, you can have utmost two apps showing on the screen at a time. However, you have to select a primary app, which occupies the majority of the screen space. The other App occupies less than 30% of the screen space. You can toggle between the views to change the sharing of screen space between these Apps.
However, there are many scenarios where one wishes to have two Apps open on the screen with each occupying half the screen. An example could be watching a lecture and taking notes at the same time. This is currently not possible in the Metro mode and I cannot understand why (I certainly do not see any technical difficulty in its implementation).
Is there a way to achieve this (without going to the Desktop view)? And if not, any clue why this is not supported?
