What I like:

• I like GNOME 40 more than GNOME 3 because it's prettier.
• I like GNOME in general because it's stable with pretty, high quality bundled programs.
• I like the UX. It takes all the good things about the macOS UX and makes them better, while taking all the bad things and making them less stupid.
• I like that they completely separate the dock from normal window management, so I never hit it when my cursor reaches the edge of the screen.
• I like that you can set Nautilus to use one-click to open folders, even though that is cribbed from Dolphin. (Even if I use lf most of the time)
• I like the simple IBus integration that lets me setup my Japanese IME easily.

What I dislike:

• I dislike that I need a system tray extension for some software.
• I dislike how in-your-face the notifications are and that they can't be stacked.
• I dislike that I need to use Dconf to set shortcuts for workspaces 5-10.
• I dislike needing GNOME Tweaks to set autostart software/daemons—this is a basic feature, not a "tweak".
• I dislike not having an easy way to port my settings for GNOME to a new computer. It's annoying to have to set all this stuff up again compared to Sway, where I clone a repository and copy some config files over.
• I dislike the new screenshot tool in GNOME 40+. It automatically saves photos to a directory, rather than letting me copy it. Come to think of it, I also dislike that it doesn't support the same screenshot protocols Sway does for grim and slurp, which is my favorite screenshot workflow.
