While brand new to Tablerone (due to a data loss using a different Tab Manager SMDHS) after reviewing many other Tab Managers, this one strikes me as my likely choice moving forward. Only wish my saved groups would keep the Chrome "Tab Group Label" (name of groups and color of group label) so they would remain easy to visually identify, as some other Managers do! Fingers crossed this feature gets added soon! Also - might you have any plans to bring Tablerone to iOS somehow for mobile on the go continuity? If Tablerone is as reliable, easy, flexible and export / import / data agnostic as I hope it will be, I'd happily pay a small reasonable monthly or yearly fee for such a tool as it's critical to my workflows (bookmarks never did quite work for me but Tab groups do!). Thanks for all you guys do and best of luck.
