I switched from GNOME 3 a long time ago, and emulating GNOME’s workflow would be the last thing I would want

Sure did. Kinda?

Moved the panel to the top, added a dock (rip latte, it’s now just a panel) and set a hot corner for the overview effect. I like it to move windows between desktops.

Everything else is default though. Maybe I changed the application launcher widget, I don’t remember.

Top bar, titlebar buttons on the left, “dock” on the right (which is just a panel), hotcorner, …

I don’t really try to replicate GNOME but rather take what improves my flow from Windows, GNOME, Unity, MacOS, …

But that’s the wonderful thing about KDE : you can choose to customize whatever you like however you feel !
