If you choose “Window” then new windows won’t open into a new tab unless you explicitly click the + or drag with your mouse. Choosing “Tab” opens any new windows invoked from your running apps into tabs.

Muting one of your web tabs is now possible: When a webpage in Sets starts playing audio, you will now be able to see a volume icon on the tab. Just click it and the audio will mute, just like in Microsoft Edge.

Tabs will now restore with better performance: You will now be able to open the tabs in the background and use no resources until you go to the tab. This means you can restore a lot of tabs at once with no issues.
