                     <summary>Does the extension work with nested structs?</summary>
                     <p>Yes. Go Memory Visualizer automatically detects and calculates layouts for nested custom struct types, giving you accurate sizes for complex data structures with embedded types.</p>

+                    <summary>What is cache line visualization?</summary>
+                    <p>CPU caches load memory in 64-byte chunks called cache lines. When a field crosses a cache line boundary, it requires two memory fetches instead of one. Our cache line visualization shows exactly which fields cross these boundaries, helping you avoid false sharing in concurrent code.</p>

+                    <summary>Can I analyze my entire codebase at once?</summary>
+                    <p>Yes. The new Workspace Analyzer command scans all Go files in your project and ranks structs by potential memory savings. Focus your optimization efforts on the highest-impact changes.</p>
