Gotham Knights is a browser-based add-on for Chrome that allows users to set an HD-ready background in their browser. You can set your browser with it on your desktop computer.

In addition, you can add a new tab to your browser by simply dragging and dropping the icon of the extension. You can customize the new tab to be of your own choice. For instance, you can create a bookmark for a website. It is possible to set it in the first place on a background color and other properties.

You can also create a new shortcut for any website that you frequently visit by dragging it to the bookmark bar. You can add the extension icon to your Home screen as quick access to the site. This will open the site right in a new tab, so you won't have to re-enter the website and the content of the page is also always up-to-date.

When you open the site in the new tab, you can customize the bottom bar with a number of options, such as search and news. You can even choose a new and different search engine from the ones already available.
