Mobile website: button to go down to very bottom of page

[d.manuk]

There’s one to scroll up, but I’d find it helpful to also scroll down, if such a feature could be added.

sorry it took forever to respond

i personally don't use the 'scroll up' button but can see how it's sort of helpful for mobile users.
all the important navigation stuff and tools are at the top of the page.

it wouldn't take long to add it, but sell me on it please
i imagine the main users of it would be mobile users, but the main downside to adding it is it eats up more screen real estate (already at a premium for mobile users!)
