With great enthusiasm, I present the idea of implementing a feature that would allow users to lock chats of their choice. I believe this functionality would bring an additional layer of security and convenience, preventing the accidental deletion of important conversations or the loss of valuable messages when performing a cleanup across multiple chats. By enabling the locking of specific chats, users would have complete control over which conversations remain untouched, regardless of actions taken in other chats. This would undoubtedly enhance the user experience, offering tranquility and organization while managing their interactions. Therefore, I earnestly request considering this suggestion, as I am confident it would significantly enhance the usability and functionality of the platform.
