- Client: threaded recursive search with wildcard matching, 2-second buffer flush for real-time progress, max depth 32 / max results 10000 - Server: local search with collect-all-then-display pattern, worker thread, time-based progress updates, partial results on stop - Toolbar: Desktop/Downloads/Home navigation buttons for both sides - Button state management via OnUpdate handlers during search - Stop vs navigate semantics with separate flags for proper cleanup - Expand environment variables in remote paths (%USERPROFILE% etc.) - i18n: add search-related strings to en_US and zh_TW language files Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
