During researching online, its common to have multiple searches running at different tabs/ windows at the same time. Navigating between tabs and windows can often be annoying and chances we may lose track or miss the flow in search. I came across this site which has the ability to run 4 Google searches in a single tab. It will be very useful for people with big screen and dual screen computers.
Site is named under www.googlegooglegooglegoogle.com. There is a green arrow, clicking it pop ups a windows asking for specific URL that you wanted to run on that specific window. A dedicated "W" icon for Wikipedia and a "X" close it if you choose to use only 3 or 2 partitions.
Additionally it also has a menu option to open closed tab, set pages on start up, always Google 4, big list of other google, side by side search.
