Jun 1, 2025June 2025 performance-focused month for victronenergy/gui-v2. This period emphasized tangible UI performance gains, a comprehensive navigation highlight overhaul, reusable component modernization, and strong code-quality efforts that improve maintainability and build performance. Business value was delivered through faster user interactions, reduced resource consumption, and simpler future changes across the GUI. Key features delivered: - Smooth and responsive UI performance across lists and navigation: smoother scrolling, dynamic/loading indicators to optimize resources, and faster page loading via asynchronous loading patterns and binding optimizations. (Commits: cf10bfa203f5de50c839ca9c8c08b78a10e5f71b; 69b80edc461bba138f26687c88e73d052148385d; f16afbd1576436a107d69b19916f03e1e4d6c810; 9abd778941257406af2d06569d9440f025b7a70e; 0fdf27607d555be29ff7802f2de33c59694d7901) - Key navigation highlight system overhaul: new GlobalKeynavigationHighlight component with simplified rendering using a single unified BorderImage for key navigation visuals.

Mar 1, 20252025-03 Monthly Summary for victronenergy/gui-v2: Focused on accessibility, security, and notification UX improvements. Delivered three main outcomes: (1) Settings Navigation Accessibility and UI Polish — broadened access to settings for users with 'User' level while preserving restrictions on non-essential items; fixed UI alignment and text overlap issues for improved readability and consistency. (2) Revamped Notification System — introduced a new notification UI and API, including a badge in the navigation bar, a dedicated status icon, improved filtering, and high-priority toasts; followed by a refactor of the notification model for maintainability. (3) Password Exposure Security Fix — removed an erroneous binding and corrected visible bindings to prevent password exposure, addressing a critical security vulnerability. These efforts reduce friction for non-admin users, enhance security, and deliver clearer event signals to users and operators.
