Feature Request: Face ID-Protected Private Folder for Chats

I’d love the ability to move selected conversations into a private folder that is hidden from the main chat history and protected by Face ID, Touch ID, or a passcode. Unlike Temporary Chat, the conversations would remain saved and accessible after unlocking the folder. The goal is to provide both privacy and organization without requiring users to delete conversations they want to keep. Potential use cases: * Health and medical discussions * Financial planning * Personal journaling * Relationship conversations * Sensitive work topics Suggested functionality: * Move existing chats into and out of the private folder * Hide chats from the main conversation list * Hide chats from search until the folder is unlocked * Optional Face ID/Touch ID prompt each time the folder is opened * Ability to create multiple private folders for organization Many users want to keep certain conversations for future reference but may not want them visible in their regular chat history. A private folder would provide a simple and secure way to manage those conversations while maintaining easy access when needed.
