What a half-assed, semi-ignorant, and sadly done review.
I spent more time reading it than he did learning the new version.
There is a dock-like applet for the panel, but you cannot manually rearrange icons there, so you need to unpin and then pin icons to get them sorted as you like.
Instead of making uninformed false statements and say that trying to screw in a screw by beating it with a hammer is the only way to do it....
How about RTFM, wiki, or maybe take 5 minutes to look at MX Tour to learn how to move pinned apps in the dock?
Furthermore, during the boot, you can see an AMDGPU error show on the screen, which is NOT there when you boot the KDE one. Hint, this would also most likely explain why Firefox isn't launching, especially if it expects to use hardware acceleration (enabled by default), and there ain't no proper firmware support, so the system can't use the GPU correctly, hence the CPU revving.
Its the same hardware support components (same drivers, same firmware) as in KDE except for the kernel! Plenty of people with newer AMD GPUs don't have an issue at all.
So hot and than cold with this guy. Its like hit or miss the type of review you get, all dependent on what Chinese Festival is taking place that week.
I don't know if he was strapped for time, was too locked into tunnel vision at the time, or is going completely senile.
Either way, I'm pretty much at the point where I am done with giving his site clicks anymore, could care less about what yet another random person on the internet has to say.
Which is exactly what he is turning into when he puts together reviews like this.
