By Braincuber Team
Published on December 28, 2025
Developer building user engagement features creates interaction disaster: user completes milestone purchase reaching VIP status but receives plain success notification making achievement feel anticlimactic losing emotional impact opportunity, form submission shows boring green checkmark instead of celebratory visual feedback reducing user satisfaction 40 percent, no visual distinction between routine actions and major accomplishments causing important events to feel mundane, and copying basic notification code from documentation results in generic experience identical to default Odoo preventing brand differentiation—creating missed engagement opportunities and underwhelming user experience from lack of custom visual effects celebrating key user actions beyond standard notifications.
Odoo 18 Custom Effects enable dynamic visual celebrations through OWL component framework integration, effect registry system registering new animations, animated particle generation with randomized properties, JavaScript interval-based position updates creating motion effects, SCSS styling for visual polish, both Python and JavaScript triggering options, user preference fallback to standard notifications, and parameter customization for messages and duration—increasing user engagement 35-50 percent through memorable visual feedback celebrating achievements making routine tasks feel rewarding through branded custom animations beyond plain success messages.

Best Practices
Respect User Preferences Always: Forcing animations on users who disabled effects equals accessibility violation frustrating users with motion sensitivity. Always check user preferences providing fallback notification. Example: users with epilepsy disabled effects but forced animation triggers seizure risk. Checking preference essential for inclusive UX.
Use Sparingly for Impact: Fireworks on every button click equals novelty wears off in 5 minutes becoming annoying. Reserve celebrations for genuine achievements first sale milestone reached major task completed. Overuse degrades perceived value making real achievements feel routine.
Keep Duration Short 2-4 Seconds: 10-second firework animation equals user waiting frustrated wanting to continue working. Optimal duration 2-4 seconds long enough for visual impact short enough user workflow uninterrupted. Longer durations should offer skip button.
