I'm in the process of migrating to CP3. Having never worked on CP2, I'm not sure how I could figure out if a custom widget is extending another widget, extending and overriding it or created from scratch.

I looked at the controller file and this is what it contains:

class LogoutLink2 extends Widget { ... }

From that I can assume that it has been built from scratch (extending from base widget class) but just wanted to have a confirmation on that.

Also, if my assumption is right, what would a widget extending/overriding another widget have in the controller?
