I’m using VSC for the first time and I’m confused by the ruler in the code. Will it prevent me from writing past it? If so, then it seems like there’s a huge unused area in the window.
I was able to remove the minimap, but I still cannot find a way to remove this huge unused space, can any one suggest how to get rid of it 
>Solution :
That line is just a visual guide. See the editor.rulers setting.
It doesn’t necessasrily wrap lines when you start to write past it, unless you also do "editor.wordWrap": "wordWrapColumn" and set "editor.wordWrapColumn" to something.
