Library statistics
Library Statistics provides a visual overview of your collection through interactive charts. Access it from the stats button in the top bar.
Overview
The top section shows summary counts for your collection: total Books, Authors, Series, Publishers, and Library Size.
A library filter dropdown lets you scope all charts to a specific library or view stats across all libraries.

Nine chart types are available. Each chart includes hover tooltips and contextual insights (peak values, averages, trends).
