I see that your Dark Theme script has UserScript annotations. Why don't you do that for your "main" script and tell people to use the Tampermonkey/Greasemonkey? Makes it a lot easier for the average joe.
I'm implementing graphing at the moment.
I wasn't even going to release it in the first place, it was more personal. But someone leaked a shitty version of it so I had to make a better one lol.
Also my scripts don't really need to be verified. I've been making PD bots since PD v2 and most people know who I am, but thanks for leaving a review of the code here! I plan on optimizing it and so on, but I've been kinda busy lately.
As for the CSS selector, they use Ember JS so the IDs are always changing. Sometimes weird things happen with the HTML structure so it won't work without the full CSS path.
As for the small function names, those are just minified jQuery libraries that need to be injected on the page. My bot has some issues with Greasemonkey because of how the scopes are seperate.
