Clojurians Log v2

I don't like github's online text editor. It messes up with my vimium's key bindings. I wrote this snippet for Tampermonkey (you can trim the outer boilerplace and just paste it into console). This snippet changes the textview so that it would not allow to place a cursor inside of it. The downside is that you can't click on the symbols but I only want to see the code when I browse. Edit: Also the scroll using vimium is lagging. The regular arrow and pgup/pgdn scroll doesn't lag... but still... There are too many unneeded elements under that text view. It's just text... whyyy

(function() {
    'use strict';

    function disableTextViews() {
        Array.from(document.querySelectorAll("#read-only-cursor-text-area")).forEach(e => {
            if (!e.disabled) {
                e.disabled = true;
                e.style.cursor = "text";
            }
        })
    }

    // 
    const MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
    var observer = new MutationObserver(function(mutations, observer) {
        disableTextViews()
    });
    observer.observe(document, {
        subtree: true,
        attributes: true
    });
})();

How do you get Conjure working on Clojure code fences in markdown files? I'd like to be able to eval code in my Clerk notebooks which use the .md extension.
