Action popup triggered from distinct visual target. Minimally disruptive to screen context. Actions are straightforward. Fast & fun. Recommendation. DO use when items have competing internal targets. DO present only the for most important and obvious actions. DO use when the item doesn’t have a meaningful detail view.

Typographical Hierarchy Typographical Hierarchy plus Indentation Principle: Grids Western world Start from top left Allows eye to parse display more easily Grids (Hidden) horizontal and vertical lines to help locate window components Align related things Group items logically Grids: Examples Grid Alignment Grid: the invisible, underlying structure of a site Grid: essential – you must use one Grid Aligment Grid Alignment Grids Help locate window components Align related things Group items logically Minimize number of controls, reduce clutter Grid Example Principles: Contrast Pulls you in Guides your eyes around the interface Supports skimming Take advantage of contrast to guide user through hierarchy of information; add focus; or to energize an interface with “texture” Can be used to .
