+## [1.6.650] – 2025-07-25
+
+- feat(Kue705FO): replace switch buttons with direct chart access buttons
+
+- Remove Schleife/TDR switch buttons and separate Messkurve button
+- Add "TDR Messkurve" and "Schleife Messkurve" buttons for direct chart access
+- Each button opens the corresponding chart type directly
+- Improve user experience by reducing clicks needed to access specific charts
+- Clean up unused imports (handleButtonClick, tdrLocation, tdrActive)
+
+---
 ## [1.6.649] – 2025-07-25
