+# Mobile Responsiveness Improvements for apps/console
+
+## Overview
+This document summarizes the comprehensive mobile and desktop user experience improvements made to the ObjectUI Console application (`apps/console`). All interfaces have been evaluated and optimized to provide excellent experiences on both desktop and mobile devices.
+
+## Design Principles
+
+### 1. Progressive Spacing
+We use Tailwind's responsive spacing utilities to progressively scale padding and margins:
+- Mobile: Smaller, compact spacing (p-3, p-4)
+- Tablet: Medium spacing (sm:p-4, sm:p-6)
+- Desktop: Generous spacing (md:p-6, lg:p-8)
+
+### 2. Flexible Layouts
+Layouts adapt from vertical stacking on mobile to horizontal arrangements on desktop:
+- `flex-col sm:flex-row` - Stack vertically on mobile, horizontally on desktop
+- `min-w-0` - Prevent flex items from overflowing
+- `flex-1` - Allow items to grow and fill available space
+
+### 3. Conditional Display
+Elements are shown/hidden based on screen size to optimize space:
+- `hidden sm:inline` - Hide text labels on mobile, show on desktop
+- `hidden sm:flex` - Hide entire elements on mobile
+- Icon-only buttons on mobile, text+icon on desktop
+
+### 4. Responsive Typography
+Text sizes scale appropriately:
+- `text-base sm:text-lg` - Smaller on mobile, larger on desktop
+- `text-xl sm:text-2xl` - Headers scale progressively
+- `truncate` - Prevent text overflow with ellipsis
+
+### 5. Touch-Friendly Targets
+All interactive elements meet minimum tap target sizes:
+- Buttons: Minimum 44x44px (h-8 to h-9 on mobile)
+- Icon buttons: Consistent h-8 w-8 sizing
+- Padding around clickable areas
+
+### 6. Mobile-First Modals
+Dialogs and sheets are optimized for small screens:
+- Full width on mobile: `w-[90vw] sm:w-150`
+- Maximum height constraints: `max-h-[90vh]`
+- Responsive padding: `p-3 sm:p-4 lg:p-6`
+
+## Components Modified

+- **Extra Large**: `≥ 1280px` (xl: prefix)
+
+## Testing Recommendations
+
+### Manual Testing Checklist

+- [ ] Test on iPad (768px width)
+- [ ] Test on iPad Pro (1024px width)
+- [ ] Test on desktop (1920px width)
+
+### Key Areas to Test
