After losing mouse gestures (which I used a lot to manage windows) I have also noticed that I can’t arrange windows and use shade/unshade. I assume it’s tied to X11 being left behind - though it really is one of the ‘killer’ features.
What’s frustrating is that it is still present and visible, but just not working…
I haven’t heard many folks shouting about this…
