As promised already, here is the code that was applied to the board before it got removed.
When you install the script, the board will look like it looked since the upgrade for everyone until yesterday, making Text readable etc.
For the script you just need to have Tampermonkey installed, then click the link and then Tampermonkey should ask you if you want to install the the script, simply click install. After that reload the board to see the changes. The code is kept really simple and has comments in it, so if you don't want a certain part (which I doubt), you can just remove everything until the next comment.
