For such a tiny change, Tab Groups make a huge difference to the usefulness of Safari.
Tab Groups, new in Safari 15 on iOS 15, iPadOS 15, and the Mac, are barely more than the bookmarks folders we’ve all abandoned and ignored for years. But a single change makes them super-useful again. Now, these Tab Groups update themselves automatically, so you never have to save a bookmark, or delete one. And it improves Safari, big time.
“Tab groups will let you better organize large numbers of open tabs. This is great for anyone who does a lot of browsing or needs to keep windows and tabs open for work or creative purposes,” Mac user and technology writer JP Zhang told Lifewire via email.
