Our Portal platform has recently undergone a significant UI and navigation revamp aimed at improving user experience. The initial change was met with panic from users who were unable to find certain features, such as notebooks and deployments, which had been moved to new locations on the sidebar. To mitigate this, visual cues like small icons and informative text were introduced to guide users through the changes. However, some users struggled to adapt to the new layout, exhibiting old habits that die hard, and required additional guidance. The experience highlighted the importance of accounting for extreme user reactions when updating UI, providing clear visual cues, and monitoring user behavior to inform future decisions.
