+## 2026-06-18 - [Optimization & Reliability]
+**Инсайт:** Синхронные вызовы `Process.Kill()` и `WaitForExit()` в UI-потоке приводили к заметным «зависаниям» интерфейса при остановке нескольких процессов (Zapret + ByeDPI/Warp). Менеджер доменов игнорировал список исключений при синхронизации с движком.
+**Действие:** Перевести все команды управления процессами в `async Task`. Использовать `WaitForExitAsync()` для неблокирующего ожидания завершения. Реализовать полную синхронизацию списков (цели + исключения) в `SyncCustomHostlist`. Внедрить debounced-сохранение настроек для предотвращения избыточной дисковой активности.
