Oh Yes! Oh Noes! The Error Buddy is now much less annoying on Khan Academy.
Oh Yes! This script will hide Khan Academy's "Oh Noes! The Error Buddy" and place his error messages in the lower right corner of the browser window.
It works on programming projects, challenges, and talkthroughs.
It currently leaves the tiny version of "oh noes" alone, because he isn't that annoying in his minimized form. I figure I'll cut him at least that much slack.
It's easy to alter the style attributes for the error messages to your liking. Just edit the appropriate lines of code:
tipbar.style.bottom = "20px";
tipbar.style.right = "20px";
tipbar.style.width = "300px";
tipbar.style.height = "auto";
tipbar.style.backgroundColor = "rgb(234, 194, 54)";
