+- What was implemented: Editor toolbar with add/save/export/import buttons
+- Files changed:
+  - src/components/editor/Toolbar.tsx - new toolbar component with styled buttons
+  - src/app/editor/[projectId]/FlowchartEditor.tsx - integrated toolbar with placeholder handlers
+- **Learnings for future iterations:**
+  - Toolbar component accepts callback props for actions (onAddDialogue, onSave, etc.)
+  - Node type buttons use color coding: blue (Dialogue), green (Choice), orange (Variable)
+  - Action buttons (Save, Export, Import) use neutral bordered styling
+  - FlowchartEditor now uses flex-col layout to stack toolbar above canvas
+  - Placeholder handlers with TODO comments help track future implementation work
