Thanks to this bug report for containing the answers, but also a "c'mon, dude" to this smug attitude:
Konsole is an app used by technical experts, and we assume that if you deliberately hide both of these UI elements, you know what you're doing. :)
Like, I get it, but also just because I know my way around a shell (as a long-time mac and linux-via-ssh user) doesn't necessarily mean I know my way around the conventions and nomenclature of your UI toolkit (as a first-time KDE user).
