Feature Request: Chat Search and 'Sort by Last Modified'

[stife]

Hello Developer Team,

I would like to request two new features that would greatly improve the user experience when managing chats:

1. Chat Search Functionality
   A search bar or a dedicated search function to find specific chats based on keywords, phrases, or content within the conversations. This would be incredibly helpful for users with a large number of chats to quickly locate relevant information.

2. Sort Chats by 'Last Modified'
   Currently, the chat list appears to be sorted by creation date. Please add an option to sort the chats by the time they were last edited or received a new message. This would allow users to easily access their most recent and active conversations.

Thank you for considering these enhancements!
