Perhaps install something like this via a custom hook where the user can
experiment with various commands that are wrapped by this
setting/settings?

In my case for instance, I render many *large* html pages AKA EBooks
with EWW/SHR, and wrapping shr/eww in my case looks like it could
definitely help.
