 ### Interactions
 
+- Colored dots directly below a date mark its events. They scale with the widget and are hidden when the calendar is too short.
 - Hover over a marked date to preview its events in a popover.
 - The advanced view replaces the month grid with a grouped event list, keeps every event attributed to its source integration, and expands titles, locations, and descriptions. Use its previous and next controls to change months.
 - If one selected integration is unavailable, its warning indicator remains visible while events from healthy integrations continue to load.
