Different products follow different design principles and technical approaches. In our case, the feature you mentioned was not included because it does not align with our current product architecture and user flow. Our design prioritizes stability, performance, and compatibility with the wider Joomla ecosystem, and implementing that specific behavior would require structural changes that could introduce conflicts or affect overall usability.
HikaShop follows its own framework and development logic, which is why they may allow that option. Each extension solves problems in its own way.
However, we truly appreciate your feedback.
