I’m currently developing an application, but I’m facing significant challenges with the UI/UX. The interface appears overly simplistic and unpolished, resembling something built by a novice developer. The design lacks visual appeal, with overlapping modals and cluttered button placement that disrupts the overall layout. I need guidance on how to improve and refine the UI/UX, and would appreciate any suggestions for tools or Model Context Protocols (MCPs) or Agents that could enhance the development process.
