Catalog -> Features -> Feature Interaction
Right now on addition of new feature interaction user is redirected to the same screen with the filled parameter. Due to this it looks like nothing happened on adding new feature interaction though the interaction gets added successfully.
Now, If we click on "update" button again to add feature interaction it gives the message "Value found, cannot create a new one".
So for better UX I think user should be redirected to the Find Interaction page on successful addition of new Feature Interaction and in case of any error user should redirected to the Add Feature Interaction page.
