<details>
<summary>For developers and advanced users (click to expand)</summary>

This method creates symbolic links for live development:

```bash
./dev-install.sh
```

**What this does:**
- ✅ Verifies Krita installation and Python support
- ✅ Installs missing dependencies automatically
- ✅ Creates development symlinks for live editing
- ✅ Provides step-by-step activation guide

#### Manual Development Setup
```bash
# Create Krita plugin directory
mkdir -p ~/.local/share/krita/pykrita

# Create symbolic links for development
ln -sf "$(pwd)/smart_segments" ~/.local/share/krita/pykrita/smart_segments
ln -sf "$(pwd)/smart_segments.desktop" ~/.local/share/krita/pykrita/smart_segments.desktop
```

## 🚨 Troubleshooting

### 🔍 Plugin Not Appearing

<details>
<summary>Click for troubleshooting steps</summary>

1. **Verify Krita Version**
   ```bash
   which krita  # Should show: /usr/bin/krita
   ```

2. **Check Plugin Installation**
   ```bash
   ls -la ~/.local/share/krita/pykrita/
   ```

3. **Monitor Krita Logs**
   ```bash
   tail -f ~/.local/share/krita/krita.log
   ```

4. **Common Issues**
   - ❌ Using Snap version of Krita (doesn't support Python plugins)
   - ❌ Missing PyQt5 bindings
   - ❌ Plugin not enabled in Python Plugin Manager

</details>

### 📦 Snap Version Issue

If you have the Snap version of Krita, you'll need to switch to the APT version:

```bash
# Remove snap version
sudo snap remove krita

# Install APT version with Python support
sudo apt install krita python3-pyqt5
```

### 🔧 Diagnostic Commands

```bash
# System check
./dev-utils.sh version

# Plugin verification
ls -la ~/.local/share/krita/pykrita/smart_segments

# Real-time log monitoring
tail -f ~/.local/share/krita/krita.log
```
