Trying to find one old message should not take half an hour
Someone sends a useful address or document, and weeks later all that remains is the memory of a conversation. Searching a common word produces hundreds of messages. Searching a specific phrase produces nothing because the wording was different. Chats are good for conversations, but they can be a poor filing cabinet. How do you save information that will matter later without saving everything? Pinning a message, adding a clear file name, or keeping one shared note might be enough. The useful system is probably the one that can be followed while things are busy.
