Worked on front end development for the decolua/9router repository, focusing on improving user experience during asynchronous operations. Addressed a specific issue where loading state icons were inconsistent, leading to visual ambiguity for users. Using React and JavaScript, implemented a targeted fix that standardized the loading indicator to always display a spinning play_arrow icon, replacing previous uses of sync or progress_activity icons. This change provided clearer feedback to users and enhanced interface consistency. The solution was delivered as a single, isolated commit, making it straightforward to review and maintain, and laying groundwork for future UX consistency improvements within the project.
