Iconography
Icons save space, and reduce cognitive load by removing the need to re-read the same piece of information against every listing, reducing friction.
What is Iconography?
All of the icons in your app should look as if they were meant to be part of a set or family, even if some of them are customized. Besides being more aesthetically pleasing, consistency in iconography removes ambiguity and helps users distinguish an icon with which they can interact from a graphic or background image with which they cannot.
