No problem. Please try this build: VisualGDB-5.6.5.4379.msi
The regular outline still shows the hierarchical structure of the source file, but you can now switch the detail view to show a plain list of all symbols, rather than local references or structure.
BTW, the Globals view in Code Explorer is extremely optimized. It can show a huge number of symbols, and allows quickly filtering them by names or types. It can also track things like references between types (e.g. all types that have fields of type X) or functions allocating/deleting types (i.e. recognizing patterns like (Type *)malloc(…)). If you haven’t checked it out yet, it’s worth a try.
