@Vivaldi Please, add cookies separation/containerization between workspaces. Now when I can stack pages it makes even more sense!
I as a Vivaldi user want to improve my productivity thanks to separate containers in every workspace:
Workspace1: Work
Workspace2: Studies
I do not want e.g. MS Teams from my work to have the same cookies as Studies. Then I need to choose and think which e-mail to login with. If it was spearate (as it should imo) I could go to Studies workspace and study and chage to Work workspace and work - being logged in only to what I need and not to everything at once. In teams it is even possible if I wanted to login to 2 separate account on facebook it is not even possible.
