Hi! @csxark
I'd like to work on this issue.

I plan to improve the user experience by implementing consistent loading, empty, and error states across the application. My work will include:

• Adding skeleton loaders for smoother loading experiences.
• Creating informative and visually appealing empty states.
• Implementing error boundaries to gracefully handle unexpected errors.
• Adding retry buttons to allow users to easily recover from failed requests.
• Improving offline support with appropriate UI feedback where applicable.

I'll ensure the implementation is responsive, accessible, and consistent with the existing design system while keeping the user experience seamless across all application states.
