- Besucher-Spalte: zeigt keine 0 an wenn kein Wert eingetragen
- Beginn-Zeit synchronisiert automatisch die Ende-Zeit
- Hintergrundfarbe auf helles Blau (#EEF4FF)
- Listen-Tab und kompakte Vorschau mit weißem Rahmen
- Besucher-Spalte schmaler, Header als "Bes." abgekürzt
- Drucken-Button im Listen-Tab, Navigation bei Druck ausgeblendet
