Turn Peeks off or change when they close

A Peek you don’t use closes after 6 hours. You can choose another time, keep Peeks until you close them, or turn Peeks off.

You leave a Peek with a recipe open on your second screen all day, and you don’t want it to close while you cook.

  1. Open Settings › Links.
  2. Under Links from other apps, choose a time in Close an idle Peek after.

The times are 1 hour, 6 hours, 1 day, and 1 week. Never keeps a Peek until you close it.

  1. Open Settings › Links.
  2. Under Links from other apps, turn off Open links from other apps in a Peek.

Links from other apps then open as a new tab in the frontmost window.

  • A Peek counts as used while it’s the window you’re in. The time counts while your computer sleeps.
  • A Peek that closes on its own leaves its page in History.
  • Peeks still close when Sval quits, whatever the time.
  • Both settings sync to your other devices.
  • Rules that send a site’s links to a Workspace apply with Peeks on or off. See Send a site’s links to a Workspace.
