They're not horrible, but outside of Gnome, they're very jarring.
It's just so dadgum unnecessary. Mutter can draw the blaster bars.
#GNOME is constantly playing the power grab game, and I'm sick of it.
Nobody wants to be Unix anymore (openness, utility, usability, interoperability), they all want to be MacOS (consolidated control, like-it-or-lump-it, one grand master vision ?)
I'm so done with the *ego* of these projects.
