Personally, not. The reason I switched to Plasma is that I didn’t like the basic layout – horizontal bar especially – and wanted a desktop environment that allowed me to customize positions and sizes of bars and so on as much as possible.

Still baffles me why they steal the screen’s usually scarce vertical real estate with a horizontal bar, instead of putting it on the side…

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.
