I don't know how to group tabs because I only do it by accident. But I do know how to ungroup them instead of deleting them. Why did I need to learn this step?
I think you need to get used to it little by little before it can be useful, honestly like any drug. But it's definitely not for everyone and could be harmful.
I'm sure it has its uses for a good percentage of people and maybe it's even worth more than $200/mo for them, but they are forcing it on the majority when it should really be a browser based option.
It's crazy that there's still nothing that comes close to Garry's Mod.
