Neuer Tab: Watch Together - gemeinsam Videos schauen (w2g.tv-Style) - Raum-System mit optionalem Passwort und Host-Kontrolle - Video-Queue mit Hinzufuegen/Entfernen/Umordnen - YouTube (IFrame API) + direkte Video-URLs (.mp4, .webm) - Synchronisierte Wiedergabe via WebSocket (/ws/watch-together) - Server-autoritative Playback-State mit Drift-Korrektur (2.5s Sync-Pulse) - Host-Transfer bei Disconnect, Room-Cleanup nach 30s Electron Desktop App (electron/): - Wrapper fuer Gaming Hub mit integriertem Ad-Blocker - uBlock-Style Request-Filtering via session.webRequest - 100+ Ad-Domains + YouTube-spezifische Filter - Download-Button im Web-Header (nur sichtbar wenn nicht in Electron) Co-Authored-By: Claude Opus 4.6 --- electron/ad-blocker.js | 87 + electron/filters.txt | 253 +
