This extension always includes tabs in tab groups. Even when you have a lot of tabs open, you can comfortably get on with the next task. With Alt + Shift + LeftArrow/RightArrow, you can swap positions with the left/right tab. With Alt + Shift + UpArrow, you can add the tab in focus to a new group. With Alt + Shift + DownArrow, you can collapse all tab groups that are not currently in focus. If you don't prefer the default shortcut keys, you can change them at chrome://extensions/shortcuts.
