[HACKTOBERFEST] Mobile App-like Interface

Mobile App-like Interface

## 🎯 Objective
Transform the interface to look more like a mobile messaging app with better touch interactions and modern UX.

## 📋 Tasks

2. Verify swipe gestures work smoothly
3. Test pull-to-refresh functionality
4. Check touch targets are large enough
5. Test haptic feedback on supported devices
