+# Quick Task 3 Summary - UI Fixes
+
+**Task:** Fix UI feedback: header, navigation, and layout issues  
+**Date:** 2026-03-13  
+**Status:** Complete
+
+---
+
+## Completed
+
+### Task 1: Fix Header branding and sizing
+- Changed "Data Station" text to "RTU"
+- Added TCK logo from `/logo/[LOGO] TCK.svg`
+- Made all header items (Solar, Battery, Time, Date, Station, etc.) same size with consistent padding
+- Reduced header height to fit better
+
+### Task 2: Fix Sidebar collapse behavior
+- Made MENU text clickable (not just the chevron icon)
+- Clicking MENU now toggles sidebar collapse/expand
+
+### Task 3: Fix RainfallView layout
+- Removed extra space before title
+- Reduced padding to fit 1024x600 screen
+- Made Last Update section visible without scrolling
+
+### Task 4: Fix GraphView layout
+- Reduced padding and spacing
+- Made chart smaller to fit 1024x600
+- Reduced stat cards size
