High constrast themes are my favourite because of it's unique color scheme/token colors. Once I got used to it I can't live without it, that's why I came up with an opinionated implementation of a high contrast theme for those who don't need that much high constrast and would rather a better looking code editor.
The font in the screenshot is Operator Mono. You can get/buy it here: http://www.typography.com/blog/introducing-operator
I use the CustomizeUI extension to customize the whole UI of VS Code.
settings.json:
{
"customizeUI.activityBar": "bottom",
"customizeUI.titleBar": "inline",
"customizeUI.activityBarHideSettings": true,
"customizeUI.statusBarPosition": "under-panel",
"customizeUI.font.monospace": "OperatorMonoLig-Book",
"customizeUI.font.regular": "OperatorMonoLig-Book"
}
