Side Views or Panes?

As well as using the concept of panes to manage nUIViewDisplay objects within a nUIWindowDisplay, it is also possible to nominate views as "side views". These can be used to provide pop-open "side menu" or "toolbox"-style functionality for an application. The table below will compare and contrast the use of panes and side views. As a general rule of thumb, side views will be more useful for phone screens than on tablet devices, but are available for both.

Side View	Panes
Pop-open when needed.	Intended to be always-open.
Will obscure or displace other content when open (possibly including nUINavViews).	Exists in its own space within the Window.
Can be defined once to provide a global pop-open "toolbox" for the entire application.	Usually changes content throughout the application's life-cycle.
Only 2 side views per Window possible at once (left and right).	Multiple panes possible.
Fixed x/y positions and height (width configurable).	Arbitrary layouts possible.
More space-efficient with smaller devices.	Better side-by-side layout of data and controls for larger devices.
Blocks interaction in other Views when visible.	Allows for interaction across multiple Views concurrently.
