Modern MPLUS Link UI Redesign

Using REFERENCE_0 as the source UI, the Teams-like internal/external collaboration system was redesigned into a simpler, more modern product model, while retaining the MPLUS Link brand, the dark blue left-side navigation bar, and the overall application functionality. A sophisticated 2-column, 3-row demo was created, showcasing six redesigned screens: 1) featuring a large main visual card and Japanese titles. We centralize collaboration with external partners through an invitation-only, dedicated workspace. 1) A welcome/login landing page with a login tab/button and a realistic desktop monitor main visual image; 2) A project bridging chat screen with right-aligned chat cards, action chips, and a message editor; 3) A team list screen simplified into two concise team cards; 4) A resource/document list screen with upload controls, search/filter areas, and file rows; 5) Titled MPI Collaborative Development Room The shared collaboration room screen includes project overview cards and a compact member/status list; 6) Titled User Management The user management screen includes user rows and a blank details panel. The new model is more spacious than the reference image: fewer table rows, increased margins, softer separator lines, a light blue-gray background, white rounded-corner cards, subtle shadows, and small blue/green accent buttons. It maintains the feel and virtual data attributes of Japanese enterprise SaaS, but removes dense and cumbersome tables, replacing them with a simplified, aesthetically pleasing UI model suitable for design improvements and comparisons. The brand name is used in the sidebar. MPLUS Link Ensure the sidebar remains consistent across all screens and avoid adding irrelevant features, watermarks, or decorative clutter.
