Seems like a great tool but for some reason, code adds on top, not on the bottom when using the graph on the right side. Which means it will add each new line on top and pushing the first line further down. I'm not sure if there is a setting for this, but in the video shown here the code adds new lines downward, which makes me believe it's not intentional that each new line added with the graph is inserted as the top line of the code.
Also, the minimap visually flickers and glitches whenever it has something to load/save and it can't be stopped without refreshing the page.
