Inertia is a Chrome extension that alters your new tab screen to show the time, weather, and a beautiful gradient that loads instantly. You can install Inertia for your browser here.
The greeting displays the time as well as your name. If you haven't set your name with Inertia, it will ask you for your name and will store it as a cookie.
The weather checks your geolocation and then looks up the weather via your latitude and longitude coordinates on https://openweathermap.org/
There are seven gradient backgrounds that rotate daily -- see which one's your favorite!
