+[MENU_STANDARDS]
+updated: 2025-12-16
+
+MENU STRUCTURE CONSISTENCY:
+  All menus follow this standard format:
+  
+  1. show_banner (clears screen + shows toolkit banner)
+  2. Menu title with icon: echo -e "${COLOR}${BOLD}🔧 Menu Name${NC}"
+  3. Empty line
+  4. Section headers: echo -e "${BOLD}Section Name:${NC}"
+  5. Empty line before options
+  6. Options: echo -e "  ${COLOR}##)${NC} 🔧 Option Name    - Description"
+  7. Empty line after section
+  8. Back button: echo -e "  ${RED}0)${NC} Back to Main Menu"
+  9. Empty line
+  10. Separator: echo -e "${CYAN}──────────────────────────────────────────────────────────────${NC}"
+  11. Prompt: echo -n "Select option: "
+
+MENU SEPARATORS:
+  Main menu: ${CYAN}═══════════════════════════════════════════════════════════════${NC}
+  Submenus:  ${CYAN}──────────────────────────────────────────────────────────────${NC}
+  
+BACK BUTTON STANDARD:
+  Always option 0
+  Always red color: ${RED}0)${NC}
+  Main menu: "Exit"
+  Submenus: "Back to Main Menu"
+
+COLOR CODING:
+  Main categories: Different colors per category
+    Security: ${GREEN}
+    Website: ${BLUE}
+    Performance: ${MAGENTA}
+    Backup: ${YELLOW}
+  Actions within menus: Consistent per type
+    Analysis tools: ${CYAN}
+    Live monitors: ${MAGENTA}
+    Actions: ${YELLOW}
+    Dangerous: ${RED}
+
+COMMON ISSUES TO STANDARDIZE:
+  
+  ❌ INCONSISTENT: Different domain/user lookup in each module
+  ✅ TODO: Create lib/domain-selector.sh with:
+     - select_domain_interactive()
+     - select_user_interactive()  
+     - validate_domain()
+     - get_domain_owner()
+  
+  ❌ INCONSISTENT: Some modules have custom menus, others don't
+  ✅ STANDARD: Modules should be single-purpose or have internal menus
+  
+  ❌ INCONSISTENT: Press Enter messages vary
+  ✅ STANDARD: Use press_enter function from common-functions.sh
+
+FUTURE IMPROVEMENTS:
+  1. Create lib/domain-selector.sh for unified domain/user selection
+  2. Create lib/menu-helpers.sh for consistent menu rendering
+  3. Audit all modules for menu consistency
+  4. Document module menu patterns in this section
