+
+TOP 5 PRIORITIES IDENTIFIED
+================================================================================
+
+1. Scale Bars (Issue #167)
+   Effort: LOW (2 weeks)
+   Impact: HIGH
+   Status: High user demand, addresses open issue
+
+2. Performance Optimization (Issue #61)
+   Effort: MEDIUM-HIGH (4 weeks)
+   Impact: HIGH
+   Status: Critical for large images, addresses open issue
+
+3. Multi-Image Curtain (Issue #80)
+   Effort: MEDIUM (3 weeks)
+   Impact: MEDIUM
+   Status: User requested, extends unique feature
+
+4. Measurement Tools
+   Effort: HIGH (6 weeks)
+   Impact: HIGH
+   Status: Major gap vs competitors
+
+5. 3D Volume Rendering (Issue #140)
+   Effort: VERY HIGH (12 weeks)
+   Impact: HIGH
+   Status: Strategic differentiator, addresses open issue
+
+================================================================================
+
+KEY INSIGHTS
+================================================================================
+
+STACKVIEW'S UNIQUE STRENGTHS:
+✅ Curtain view - Unique interactive comparison tool
+✅ Simple API - Lowest learning curve in the space
+✅ Jupyter-native - No separate application needed
+✅ Lightweight - Fast startup, minimal dependencies
+✅ Interactive exploration - Great for teaching
+
+CRITICAL GAPS TO FILL:
+❌ No scale bars (Issue #167) - High demand
+❌ Poor large image performance (Issue #61) - Critical issue
+❌ No 3D rendering (Issue #140) - Strategic gap
+❌ No measurement tools - Missing professional feature
+❌ Limited annotations - Needs improvement
+
+STRATEGIC DIRECTION:
+→ Maintain: Simplicity, Jupyter focus, lightweight approach
+→ Add: Professional features (measurements, 3D, scale bars)
+→ Avoid: Feature bloat, competing with napari, breaking changes
+
+MARKET POSITION:
+Stackview should be the "easy napari" for quick interactive exploration
+in Jupyter, not trying to match napari feature-for-feature but focusing
+on simplicity and ease of use.
