If kaddressbook is configured with multiple address books, entries from all of them are displayed in the same color, and cannot be easily distinguished without clicking a single entry and looking at it's details. In korganizer, events from different calendars are displayed in different (configurable) colors. I would love a similar feature in kaddressbook. Kaddressbook 5.24.2 KDEFrameworks 5.110.0 Qt 5.15.10
