Create a Workspace

A Workspace holds its own tabs and groups. Each window shows one Workspace, and its color tints the window and the home page.

You’re starting a project and want its tabs kept apart from your everyday ones, so you make a Workspace called Work.

  1. At the top of the panel, select the current Workspace’s name.
  2. At the bottom of the list, choose New Workspace….
  3. In Name, type a name for the Workspace.
  4. Optional: select Emoji, then choose another emoji.
  5. Optional: under Color, select a color.
  6. Select Create.

The window goes to the new Workspace, which starts empty.

  • Sval starts you with a random emoji. To remove it, select Emoji, then choose No emoji.
  • Sval Default is the color a Workspace has until you pick another.
  • To give the Workspace its own cookies and sign-ins, check Isolate this Workspace before you select Create. See Isolate a Workspace.
  • Your Workspaces sync to your other devices, along with their tabs and groups.
  • You can also make a Workspace while moving a tab. See Move a tab to another Workspace.
  • New Workspace has no keyboard shortcut until you give it one in Settings › Keyboard shortcuts.
  • Name can’t be empty. A Workspace needs a name. Type one, then select Create again.
