Finding information is essential, whether you're a new user trying to figure out where to start and what to do or an experienced user looking for a parameter for a command. The organization, retrievability, and visual effectiveness of information contribute most to whether users can find the information that they need.

Retrievability
The presentation of information in a way that enables users to find specific items.
Visual effectiveness
