How to make theme.js less heavy?

[RoneoOrg]

Hi there,

I've been surprised by the file /static/theme.js: it seems to be minified but still, 1.7Mo!

I couldn't understand precisely the content, even with an automatic reformatting in Vscode.

Is this file documented somewhere? (I searched this whole repo but found nothing)

Is there a way to disable some parts of this JS, even if some features are affected?

(I'm aware of the param enableMomentJs)

Here is the readable theme.js file: https://github.com/Lednerb/bilberry-hugo-theme/blob/master/assets/js/theme.js, and it's self-explaining.
