 ## ✨ Ключевые возможности
 
 ### 🤖 Telegram Бот
 - **📅 Создание расписаний (Batch Sessions)**: Создавайте сразу несколько игр одним сообщением (на неделю или месяц вперед).
-- **✋ Интерактивная запись**: Игроки записываются на конкретные даты нажатием одной кнопки.
+- **✋ Интерактивная запись и выход**: Игроки записываются на конкретные даты и самостоятельно снимают запись нажатием одной кнопки.
+- **👥 Лимит мест и лист ожидания**: ГМ задаёт максимальный состав, бот не переполняет сессию, автоматически ведёт очередь ожидания и освобождённое место отдаёт первому ожидающему.
 - **📁 Поддержка Форумов (Telegram Topics)**: Бот автоматически создает тему во вложенных чатах Telegram под каждую новую пачку игр.
 - **❌ Управление сессиями**: Мастер может отменять отдельные игры прямо в общем сообщении расписания.
 - **🗓 Экспорт в Календарь**: Генерация файла `.ics` для добавления всех игр в Google, Apple или Яндекс Календарь одной командой.
@@ -19,6 +22,8 @@
 ### 🌐 Web Dashboard (Blazor Server)
 - **🔐 Авторизация через Telegram**: Безопасный вход с использованием Telegram Login Widget (HMAC-SHA256 валидация).
 - **📝 Удобное редактирование**: Веб-интерфейс для детального редактирования сессий, изменения дат, названий и статусов.
+- **🧩 Bulk-операции для Batch Sessions**: ГМ может обновить общий title/link, перенести всю пачку на фиксированный шаг и клонировать batch на следующую неделю или месяц.
+- **⬆️ Управление очередью**: Веб-интерфейс показывает заполненность, лист ожидания и позволяет ГМу поднять первого игрока из очереди.
 - **🔄 Автоматическая синхронизация**: Любые изменения в веб-интерфейсе мгновенно обновляют сообщения с расписанием в Telegram-чатах игроков.
 - **🕒 Управление временем**: UI адаптирован под московское время (UTC+3), в то время как база данных работает в UTC.

+Строка `Мест:` необязательна. Если она указана, игроки сверх лимита попадут в лист ожидания, а ГМ сможет повысить первого ожидающего через кнопку в Telegram или Web Dashboard.
+
+Игрок может самостоятельно снять запись кнопкой `🚪 Выйти` в сообщении расписания. Если он был в основном составе и в листе ожидания есть игроки, бот автоматически переводит первого ожидающего в основной состав и обновляет сообщение пачки.
+
+### Bulk-операции в Web Dashboard
+На странице группы Web Dashboard показывает отдельный блок для каждой пачки игр. ГМ может:
+- обновить общий `title` и `link` сразу у всех сессий batch;
+- перенести пачку, задав новую первую дату и фиксированный шаг между играми в днях;
+- клонировать batch на следующую неделю или следующий календарный месяц.
+
+После редактирования или переноса исходное Telegram-сообщение расписания перерисовывается. При клонировании создаётся новая пачка с новым Telegram-сообщением и пустым составом игроков.
+
 ### Другие команды
 - `/listsessions` — Показать список всех актуальных игр в этой группе.
 - `/reschedulesession` — Перенести сессию на другое время с голосованием игроков.
