Monthly Summary — 2025-01: Focused on stabilizing Wayland experiences, UI polish, and hardening plugin loading across dde-shell, dde-tray-loader, and Siyuan. Delivered three sets of outcomes: key features with UX improvements, critical bug fixes for Wayland-related issues, and safety hardening to plugin loading that reduce runtime conflicts. These efforts improved user experience, reduced visual glitches, and strengthened cross-application compatibility, aligning with business goals of stability, customer satisfaction, and platform readiness. Key deliverables by repository: - dde-shell: Dock panel visual enhancements with item-centering animations and a safety-focused boolean config refactor to improve reliability when item counts change; temporary groundwork to align with window-splitting efforts. - dde-tray-loader: Treeland Wayland plugin loading safety — introduced a blacklist to skip problematic plugins in Wayland sessions, reducing conflicts and startup risks. - siyuan: PWA Titlebar UI enhancement — refined titlebar to fill the full page width and harmonize styling with native apps for a consistent user experience across platforms. Impact: Improved Wayland stability and UI consistency, safer plugin loading in Wayland, and better PWA integration, contributing to lower support incidents and smoother onboarding for new users. Technologies/skills demonstrated: UI animation and polish, cross-repo coordination, boolean config refactor for safety, Wayland-specific stability hardening, PWA UI refinement, and changelog awareness.
