For such a small change, tab groups make a big difference in Safari's usability.
How to Use the New Safari Tab Features on Your Mac
Tab Groups, new in Safari 15 on iOS 15, iPadOS 15, and the Mac, are little more than the bookmark folders we’ve all neglected and ignored for years. But one single change makes them super useful again. These tab groups now update automatically, so you never have to save or delete a bookmark. And it improves Safari dramatically.
"Tab groups let you better organize large numbers of open tabs. This is great for anyone who does a lot of web 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.
Bookmarking used to be a time-consuming task, which is why so few people do it. Maybe a folder of favorite sites to display on the home page, but that's about it.
