KDE Human Interface Guidelines

The KDE Human Interface Guidelines (HIG) offer designers and developers a set of recommendations for producing beautiful, usable, and consistent user interfaces for convergent desktop and mobile applications and workspace widgets. Their aim is to improve the experience for users by making application and widget interfaces more consistent and hence more intuitive and learnable.
