@leocg I tried workspaces but it is very intransparent as you never really know that there actually is something in a workspace unless you open it and look inside. I really wanted to get accustomed to it, but I rather just used different windows instead, because 1: you know there IS a window with extra content and it is actually used. 2: windows lets you "peek" and see whats inisde in that windows.
But Tab groups are right there besides the other tabs and super quickly accessible. It just speeds up the tedious work of managing your open webpages tremendously.
I first saw this on my Spanish colleagues computer who is using chrome. Then I had to work on two different Jira accounts and have used Edge for that which also has this feature and experienced it myself.
Tab grouping, like Chrome and Edge does it, may be the biggest killer feature for someone like me, a freelancer and private person, working on multiple projects at once and having so many tabs to manage.
And I really tried to use workspaces, but it's essentially not really different to use multiple windows.
You can achieve many tasks in different ways, they only difference is the User Experience. And the UX for tab groups is excellent compared to every other tried solution I came across so far (being on the internet since 1996)
