One of these tools that just works so well you forget it's there

Cool and working

even enhances youtube darkmode this is a blessing

终于找到这种软件了

This is the near-effortless experience I've been looking for. After messing around with add-ons like Stylish and often failing to find styles that still functions, this is a breath of fresh air that _just works_ 98% of the time. My main request would be to be able to set "Only for x.y" as the default so I can fine tune pages without worrying about upsetting the default.
