Redesign: I've responded to the redesign argument in another comment. It's easy to find if you search the page for "rare event".

Mobile app: this is addressed in the article.

Naming: Usually most naming for different parts of pages is handled by the design(er), but even if not, once you have an approximate naming convention for parts of the site, naming becomes easy. And the stakes for these names aren't that high, because you are only scoping everything down to a single page, so global consistency and precision in naming is not that imporant. It just needs to be enough for someone to understand what it most likely refers to on this page.
