clean up deleted conversations
When a conversation is deleted, it should be removed from the thread. If the conversation is a top level conversation, there's nothing more confusing than to see replies and nothing to put them in context.

you can also copy those messages from your feed. Double click the message, then Copy/Paste(Ctrl+C / Ctrl P)... selects whole message not just the concatenated text. Which seems like a bigger problem...
