The only other two I need are Monday start and pop tiling.
And IdeaPad mode for my Legion for the power options.
I understand from the video that generally there is better performance under wayland. Right?
Touchpad gestures. 
Irregardless of Wayland i would never switch from Kde to Gnome whether it uses Xorg or Wayland. It’s not the desktop i would ever choose. I’d rather use Windoze. 
Not a problem with Xorg, but with GNOME not implementing it for Xorg sessions. Supposedly there are extensions that let you use touchpad gestures on Xorg in GNOME.
As a KDE user, it seems it is not easy for KDE users to switch to Gnome.
I take this a s a joke. I see it impossible for me to go back to windoze… no matter what desktop it is!
It’s a bit like driving a Ferrari and then switching to a Lada. You get spoiled.
I had set up plasma to use touchegg. It was nowhere near as good
I wouldn’t know, I don’t use a touchpad. But I am fairly sure it’s not an intrinsic limitation of Xorg.
The same is valid about GNOME 
There are dozens of us! DOZENS!
Me either… i use only mouse. I don’t like touch anything, Touchpad, touch screen whatever… 
There are 10 types of people. Those that use Gnome and 9 that don’t!
Edit: Once you get your Kde going on there’s no going back! It’s plasma all the way!
Yes, and seems logical to me as Gnome is a unique experience and design as a desktop.
It may be harder for Gnome guys to convert to KDE, than it is harder for KDE to convert to Gnome.
I feel the same on my GNOME!
Kde frameworks 5.99 just came through. Now i wait for Kde Plasma 5.26 You get Gnome 43 yet? 
I hate touch pads, though touch screens for me are just to touch the close, OK, cancel buttons. No more.
I am not a “monogamous” ARCH user
I roll with other distros as well
I roll with the Kde Kid’s! We got lots of plasma.
Yeah.
That’s an “in-group” thing!
