Enable response folding so longer conversations can be more easily scanned

[upnix]

In the same way you can fold headings in Obsidian, I'm imagining the ability to fold AI responses to questions. I think the question I asked would stay visible, but I could hide or unhide the response.

Jupyter notebooks handle this well where you can entirely fold, or just partially "fold" command output (output is truncated).

I think this would make scanning long conversations a lot easier. I find the saving and loading of past conversations a little cumbersome, so conversations that could have been broken up into distinct chats are frequently happening in long, single conversations.
