Passing params on App run?

[wlasson]

I've been trying to think of a way to have different views loaded for
a module, which in turn is loaded by the page controller. I was
wondering if it would be possible to actually pass a parameter through
on $app->run()?

So for example:

$app->run('/index?display=module'); or $app->run('/index?
display=full');

Maybe it is passed using the optional parameter with run()?

Thanks in advance.
