Version 2.1.33 worked fine, browse, add, preview, opened in tabs in the same window.

With 2.1.34 tabs are gone, and right clicking on the windows no longer offer the option to view the tab bar.

Is this due to a change in the GUI toolkit version?

2.1.35 was released today, and it should resolve this issue by rolling back the toolkit.

This is a problem again in 2.1.54 with macOS Monterey 12.5.1.  
I’m not able to use Anki with a tabbed interface even though I set “Prefer tabs: always” in System Preferences \> General.
