Most of your users are using a small fraction of your product. The Pareto Principle, the observation that roughly 80% of effects come from 20% of causes, first made by Italian economist Vilfredo Pareto in the late nineteenth century regarding wealth distribution, applies with striking consistency to digital product usage. Usage analytics typically show that a small number of features account for the overwhelming majority of interactions. This is not a problem to be solved. It is a structural reality that should directly shape design prioritisation, visual hierarchy, and resource allocation.
