Well, in short, a lot of those things you mention are intentional omissions. Table of Contents are somewhat unnecessary when headings are collapsed by default. Tabbers provide a poor mobile experience, not just on Fandom but on any website, which is why there are globally recognized design and user experience guidelines on how they can and should be used properly — our version of Tabbers can't meet these criteria. We have — I know that I in particular have — spent a few years illustrating how to make templates not get broken on mobile. I know that we are open to evolving the reading experience on mobile, but that has to be done carefully as adding too many bells and whistles seriously impairs the usability for readers.
