Were there any cases where you had to communicate a feature that was not in the task?

Yes, such cases happen. For example, during feature development, additional requirements or improvements are often identified that were not initially specified in the task but significantly enhance quality or usability. In such cases, it is important to discuss with the team and the manager to agree on adding these changes. This could be, for example, an improvement in form validation, adding animation for better UX, or optimizing data loading.
