I mean a separate window with a predefined set of tabs that could be for your work or leisure. no longer having to keeping multiple windows open and switching between them for office work and personal one. if there could be a handy switch, it would be amazing. kinda like how Arc browser has spaces. it's so intuitive. and so helpful. right now the only alternative is to create multiple tabs and then close the window and go search for it in the Recently Closed Windows tab. that's just bad.
