Great suggestions so far! I’ve also come across ‘Toby for Chrome’, which isn’t exactly like ‘Tree Style Tab’ but has some similar features that could work for you. It’s more of a visual organizer, where you can group tabs into customizable collections.
You can drag and drop tabs into these collections, which makes managing your tabs really intuitive, especially if you’re more into organizing visually rather than nesting them in a tree structure. It doesn’t support automatic nesting, but it’s still a solid option if you’re looking to store and organize your tabs for future sessions.
