Google Chrome’s tab groups feature finally started rolling out to all users last week. The feature was announced earlier this year and is designed to save you a whole lot of time if you keep dozens of tabs open at once. Google is planning to automatically create a tab group if you open multiple tabs with the same domain. Currently, you need to manually create a group and drag open tabs across the group strip to bring them inside the same group. This could save your time trying to find the Wikipedia pages.
