I noticed too that the scroll was a bit blending with the background but I thought the text next to it, would make people notice it. The graph is also something I wanted to improve on but I failed to figure out how to manually arrange the nodes within the editor, so I just auto arranged it. It didn't look as clean as my local one.
But now that I think about it, I could have just taken a screenshot and covered the text with a rectangle. Modern problems require modern solutions.
