Essentially type checking to see if I should display some additional 
features. For example:
(self activeComponent currentGallery) = self rootGallery
        ifTrue: [
            html divNamed: 'random_images' with: [ self 
renderRandomImagesOn: html ].
            html divNamed: 'latest_images' with: [ self 
renderLatestImagesOn: html ].
        ].

There are better ways to do this, but this is convenient for now. I'm 
still trying to learn how Presenters, Components, and Decorations work 
together.
