Problem
* Many visual representations of unresolved tasks or objects on a screen can create anxiety in users.
* The horizontal layout of SFW lends itself to this.
* There are no tools to manage the clutter - you can't hide / remove open pages.
* There is a UI concept of "focus" at work here, but almost no visual hierarchy change to accommodate it.
Possible Solutions
* Real question: What is the user actually doing when they have multiple pages set up? What use cases do we need to prioritize here?
* Have the focused page take a central view on the screen?
* Hide unfocused pages in a list or small multiples?
