"Sticky" / quickly accessible header (actions)

[Morgy93]

You must manually scroll to the very top to access the header for using the theme switcher and search.

It would be great if the header is sticky or at least pops in if you scroll up a bit so that you have quick access to features in the header.

Example: https://docusaurus.io/docs/markdown-features/code-blocks
If you scroll down and afterwards up a little, the header pops back in. Desktop and mobile.

That's a cool feature, I agree. The search is also always triggerable with cmd + k.
