 ## ✨ Основные возможности
 
-- **🔀 Раздельный мульти-поиск по тегам**: Ввод нескольких тегов через пробел обрабатывает каждый тег независимо, выдавая контент по обоим тегам в одной ленте.
-- **➕ Локальный оператор `and`**: Для строгого объединения тегов на одном арте достаточно написать между ними `and` (например: `genshin and raiden`).
+- **🎯 Общие модификаторы в мультипоиске**: При вводе `cat and dog anthro` модификатор `anthro` автоматически применится к обоим тегам (`cat anthro` + `dog anthro`).
+- **🔀 Раздельный мульти-поиск по тегам через `and`**: Оператор `and` опрашивает серверную базу по каждому тегу независимо и плавно чередует посты обоих тегов в общей ленте.
 - **🌐 Pawchive в главной ленте**: Глобальная лента недавних постов с Pawchive подключена прямо в общий Feed наравне с Rule34, Gelbooru, e621 и Realbooru.
 - **🏷️ Интерактивные теги автора**: Быстрая фильтрация по темам с живыми счётчиками постов (`#tag (count)`).
 - **📢 Анонсы и новости авторов**: Всплывающее окно анонсов автора с датами и текстом обращений к аудитории.
