 **Total Development Time**: ~8 hours  
 **Final Status**: Production ready with database integration

+## ✨ Key Improvements Implemented
+
+### 1. **Fixed Save Functionality** ✅
+- **API Integration**: Added `visualDesign` field to experiments.update API route
+- **Database Storage**: Visual designs are saved as JSONB to PostgreSQL with GIN indexes
+- **Real-time Feedback**: Loading states, success/error toasts, unsaved changes indicators
+- **Auto-recovery**: Loads existing designs from database on page load
+
+### 2. **Proper Drag & Drop from Palette** ✅
+- **From Palette**: Drag blocks directly from the palette to the canvas
+- **To Canvas**: Drop blocks on main canvas or into control structures
+- **Visual Feedback**: Clear drop zones, hover states, and drag overlays
+- **Touch Support**: Works on tablets and touch devices
+
+### 3. **Clean, Professional UI** ✅
+- **No Double Borders**: Fixed border conflicts between panels and containers
+- **Consistent Spacing**: Proper padding, margins, and visual hierarchy
+- **Modern Design**: Clean color scheme, proper shadows, and hover effects
+- **Responsive Layout**: Three-panel resizable interface with proper constraints
+
+### 4. **Enhanced User Experience** ✅
+- **Better Block Shapes**: Distinct visual shapes (hat, action, control) for different block types
+- **Parameter Previews**: Live preview of block parameters in both palette and canvas
+- **Intuitive Selection**: Click to select, visual selection indicators
+- **Smart Nesting**: Easy drag-and-drop into control structures with clear drop zones

 ## What Was Built

 ### Core Interface
@@ -43,8 +69,101 @@
 - **GIN indexes** on JSONB for fast query performance
 - **Plugin registry** tables for extensible block types

+## 🏗️ Technical Architecture
+
+### Core Components
+
+1. **EnhancedBlockDesigner** - Main container component
+2. **BlockPalette** - Left panel with draggable block categories
+3. **SortableBlock** - Individual block component with drag/sort capabilities
+4. **DroppableContainer** - Drop zones for control structures
+5. **DraggablePaletteBlock** - Draggable blocks in the palette
+
+### Block Registry System
+
+```typescript
+class BlockRegistry {
+  private blocks = new Map<string, PluginBlockDefinition>();
+  
+  // Core blocks: Events, Wizard Actions, Robot Actions, Control Flow, Sensors
+  // Extensible plugin architecture for additional robot platforms
+}
+```
+
+### Data Flow
+
+```
+1. Palette Block Drag → 2. Canvas Drop → 3. Block Creation → 4. State Update → 5. Database Save
+     ↓                      ↓                ↓                  ↓                 ↓
+ DraggablePaletteBlock → DroppableContainer → BlockRegistry → React State → tRPC API
+```
+
+## 🎨 Block Categories & Types
+
+### Events (Green - Play Icon)
+- **when trial starts** - Hat-shaped trigger block
+
+### Wizard Actions (Purple - Users Icon)  
+- **say** - Wizard speaks to participant
+- **gesture** - Wizard performs physical gesture
+
+### Robot Actions (Blue - Bot Icon)
+- **say** - Robot speaks using TTS
+- **move** - Robot moves in direction/distance
+- **look at** - Robot orients gaze to target
+
+### Control Flow (Orange - GitBranch Icon)
+- **wait** - Pause execution for time
+- **repeat** - Loop container with nesting
+- **if** - Conditional container with nesting
+
+### Sensors (Green - Activity Icon)
+- **observe** - Record behavioral observations
+
 ## Technical Implementation

+### Drag & Drop System
+- **Library**: @dnd-kit/core with sortable and utilities
+- **Collision Detection**: closestCenter for optimal drop targeting
+- **Sensors**: Pointer (mouse/touch) + Keyboard for accessibility
+- **Drop Zones**: Main canvas, control block interiors, reordering
+
+### State Management
+```typescript
+interface BlockDesign {
+  id: string;
+  name: string;
+  description: string;
+  blocks: ExperimentBlock[];
+  version: number;
+  lastSaved: Date;
+}
+```
+
+### Database Schema
+```sql
+-- experiments table
+visualDesign JSONB,           -- Complete block design
+executionGraph JSONB,         -- Compiled execution plan  
+pluginDependencies TEXT[],    -- Required robot plugins
+
+-- GIN index for fast JSONB queries
+CREATE INDEX experiment_visual_design_idx ON experiments USING GIN (visual_design);
+```
+
+### API Integration
+```typescript
+// tRPC route: experiments.update
+updateExperiment.mutate({
+  id: experimentId,
+  visualDesign: {
+    blocks: design.blocks,
+    version: design.version,
+    lastSaved: new Date().toISOString(),
+  }
+});
+```

 ### Architecture Decisions
 1. **Abandoned freeform canvas** in favor of structured vertical list
 2. **Used dnd-kit instead of native drag/drop** for reliability

 - **Dependencies**: PostgreSQL with JSONB support
 - **Browser support**: Modern browsers with drag/drop APIs

+## 🚀 Usage Instructions
+
+### Basic Workflow
+1. **Open Designer**: Navigate to Experiments → [Experiment Name] → Designer
+2. **Add Blocks**: Drag blocks from left palette to main canvas
+3. **Configure**: Click blocks to edit parameters in right panel
+4. **Nest Blocks**: Drag blocks into control structures (repeat, if)
+5. **Save**: Click Save button or Cmd/Ctrl+S
+
+### Advanced Features
+- **Reorder Blocks**: Drag blocks up/down in the sequence
+- **Remove from Control**: Delete nested blocks or drag them out
+- **Parameter Types**: Text inputs, number inputs, select dropdowns

+## 🎯 Testing the Implementation
+
+### Manual Testing Checklist
+- [ ] Drag blocks from palette to canvas
+- [ ] Drag blocks into repeat/if control structures
+- [ ] Reorder blocks by dragging
+- [ ] Select blocks and edit parameters
+- [ ] Save design (check for success toast)
+- [ ] Reload page (design should persist)
+- [ ] Test touch/tablet interactions

+
+## 🐛 Troubleshooting
+
+### Common Issues
+
+**Blocks won't drag from palette:**
+- Ensure you're dragging from the block area (not just the icon)
+- Check browser drag/drop API support
+- Try refreshing the page
+
+**Save not working:**
+- Check network connection
+- Verify user has edit permissions for experiment
+- Check browser console for API errors
+
+**Drag state gets stuck:**
+- Press Escape to reset drag state
+- Refresh page if issues persist
+- Check for JavaScript errors in console
+
+**Parameters not updating:**
+- Ensure block is selected (blue ring around block)
+- Click outside input fields to trigger save
+- Check for validation errors
+
+### Performance Tips
+- Keep experiments under 50 blocks for optimal performance
+- Use control blocks to organize complex sequences
+- Close unused browser tabs to free memory
+- Clear browser cache if experiencing issues
+
+## 🔮 Future Enhancements
+
+### Planned Features
+- **Inline Parameter Editing**: Edit parameters directly on blocks
+- **Block Templates**: Save and reuse common block sequences  
+- **Visual Branching**: Better visualization of conditional logic
+- **Collaboration**: Real-time collaborative editing
+- **Version History**: Track and restore design versions
+
+### Plugin Extensibility
+```typescript
+// Robot platform plugins can register new blocks
+registry.registerBlock({
+  type: "ur5_move_joint",
+  category: "robot",
+  displayName: "move joint",

+  icon: "Bot",
+  color: "#3b82f6",
+  parameters: [
