Since 2.0, the window is no longer hiding by itself when losing focus. It doesn’t seem to behave like the other system windows. It doesn’t appear in the quick app switcher (Cmd + Tab), and when I swipe to another macOS desktop space with my trackpad, I see it briefly above all the other windows no matter what before going background, which creates a visual glitch.

If an opt-in is possible to get auto-hiding like before (v1.X) I would take it or at least being visible in macOS quick app switcher.
