Make horizontal scrollbar more visible in Visual Studio code

You can give it a more obvious color:

 "workbench.colorCustomizations": {
    
    "scrollbarSlider.background": "#ff0000",
    "scrollbarSlider.hoverBackground": "#0088ff",

}

There are a couple more scrollbar color settings you can try, these affect both vertical and horizontal scrollbars though.

As of v1.58 see https://stackoverflow.com/a/46634103/836330 for more officially exposed scrollbar settings including

editor.scrollbar.verticalScrollbarSize
editor.scrollbar.horizontalScrollbarSize

,"editor.scrollbar.verticalScrollbarSize": 10
,"editor.scrollbar.horizontal": "visible"
,"editor.scrollbar.horizontalScrollbarSize": 15
