I think this is a very common model, and am curious too how others 
handle this.

The way I would like to do it, is to have a module for the tabs that 
would also inherit from C::A. It would be driven by a second runmode 
parameter (say, 'tab'), and return its output back to the main App.
	
so in search you would do something like

	use App::Tab;
	return App::Tab->new()->run;

I can imagine doing the same modularity for the actions, if that is 
worth it.
Now that I think of it, this sort of resembles the way you'd do 
traditional GUI programming. The main app has some menu items that call 
up dialogs/screens, which are selfcontained modules.
Of course, this requires that the $ENV{OUTPUT_RETURN_ONLY} be wrapped in 
a method, so that you can turn it on and off on a per object basis. ;^)
