July 2025: Delivered two user-facing features and completed routine maintenance across two repositories. The Raycast Wallpaper Desktop Extension enables fetching and setting Resend wallpapers as the desktop background with manual/automatic switching, user appearance and exclusion preferences, and grid/list browsing views. A new image loading optimization introduced a centralized getThumbnailUrl utility, improving load performance across grid, list, and preview components. In addition, maintained dependencies by bumping resend-node to 4.7.0 to ensure compatibility and stability. Overall, these efforts reduce load times, enhance user personalization, and improve maintainability and ecosystem alignment.
