User feedback 'Closed Loop Award'. After suggestions are adopted, track the optimization effects: resolution rate over 90%, high user praise, then issue the 'Implementation Award' WCT. A user suggested 'night mode is too bright', after the modification, the praise was overwhelming, and the secondary reward was more solid. This kind of 'feedback has a beginning and an end' is better than forgetting after making a suggestion; the improvement of the ecosystem is forged together by users and the team.
