Condense/collapse large messages (messages crossing screen height)

[Ezio-Sarthak]

After the recent merge of #874, we do now have a way to view large messages, i.e., messages that cross the terminal height boundaries. For such large messages, we could show a condensed/collapsed view, so that it doesn't clutter the other messages in the list. The height of the message could be shrunk to a default visible one.

There might be a flag for messages for this which we could probably adapt too. That said, this might need investigation as to how web app handles such behavior.
