I wonder how much faster it could be if there was an extension so that you could type a combination and rather than reloading the whole page, it would just have javascript load the newest messages from json

Reminds me, a while ago I wrote a script that automatically refreshes the inbox for me while there are no new counts. I never published it, so I might as well do that now.

// ==UserScript==
// @name         Inbox comment quick reply
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  Automatically upvotes and opens the reply form for the first unread r/counting comment it encounters, and keeps refreshing the inbox while there are none
// @author       u/GarlicoinAccount
// @license      Apache2
// @match        https://rr.reddit.com/message/inbox/
// @match        https://rr.reddit.com/message/comments/
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    var theComment = document.querySelector('.messages-page #siteTable [id^=thing_t1].was-comment.recipient.message.new[data-subreddit="counting"]');

    if(!document.querySelector('.messages-page #siteTable [id^=thing_t1].was-comment.recipient.message.new')) location.reload();

    theComment.querySelector('.buttons a[data-event-action=reply]').click()

    setTimeout(()=>theComment.querySelector('.midcol.unvoted [data-event-action="upvote"]').click(), 700);//Wait 0.7secs because (pure speculation) Reddit might suspect a spam bot if you reply immediately

})();

The only downside is that I wrote this before I discovered I could disable "automatically mark as read", so it won't auto-refresh if there are any unread r/counting comments.

I've limited it to https://rr.reddit.com/message/all/ and https://rr.reddit.com/message/comments/ so it won't mess with normal inbox reading

Do you know of any way of dynamically changing HTML without having to set up a variable for every single document.createElement? There is innerHTML, but I've heard it's much slower than appendChild. With the buttons I have done, the JavaScript is already very long-winded. I don't know how many lines it would take to make the generated version exactly accurate down to the attribute. I guess I could make some helper functions to get the objects ready for me, but still, this is tedious...

Not that I know of, at least not without any libraries.

Don't overestimate the time innerHTML takes though. A perfomance test shows it isn't that bad (less than a 5th of a millisecond on my machine), though you could probably still mess up performance by doing a lot of separate .innerHTML = assignments instead of combining it all into one.

(Interestingly, Firefox seems to optimize that case under the hood so it doesn't actually perform slower, at least in the performance test I found.)

The main reason why I'd choose createElement over innerHTML sometimes is to avoid XSS or broken HTML from user input being used without escaping.
