I tried out the new desktop mode on my Pixel 9a over lunch. It's a pretty decent first release. The window management is pretty good, with options for floating, half tiling, and multiple desktops. I couldn't work out how to move an app between desktops though. It doesn't seem to support HiDPI scaling, or maybe it doesn't support 4K. Connected to my 4K screen it outputs 1080p. Also not sure how you take screenshots. These are stills from a HDMI capture.
