One thing that's infuriating me is that apparently it's now impossible to implement in modern GNU/Linux distros as Wayland does not allow applications (such as file managers) to position windows.
Yeah, really.
And by "not allow" I don't mean "they haven't gotten around to it", they've actually said they're opposed on principle in the mailing lists.
We are running so fast in the wrong direction with UI design it's not funny. GNOME wanted to try something new, and I respect that, but it's like they took everything we've learned about what makes a good UI in the last 40 years, and did the exact opposite. It's one thing to change where the scrollbars are, or decide whether to put menus at the top of the screen or not, or what buttons should look like, etc, but they don't even value concepts like consistency any more.
It's horrific.
