KDE Visual Design Group/KirigamiHIG/Principles/Navigation
Kirigami aims for clear and predictable navigation through information spaces, as well as clear action patterns.
One central element for clear navigation that is Column-based navigation, which allows users to navigate up and down through levels of hierarchically organized information spaces in a consistent manner, and allows them to quickly step through elements in a list while seeing each element's details on larger screens.
Actions are clearly separated into global and context-specific ones, to make the scope of an action always clear and to allow users to intuitively know where to look for an action.
