The way they did it though… the tab group name cant be collapsed so it takes a lot of room. I find I’m still using task oriented groups from the Simple Tab Groups extension, and then using the new core groups feature as a way to group subtopics for that task.

And before you say “you must have a million tabs”… I used to have millions of tabs, but now i average less than 100 when I have a lot of tasks I need to balance, and I know what all of them are open for. So when I complete a task I delete the Simple Tab Group and say bye to all those tabs.
