I second having an option to show the last query not just for 5 minutes, but always be shown, even after an hour. For me, 5 minutes is often not enough time and I often have to use the arrow keys to get it back. In that situation the "show latest history" feature is useless to me. Like otijhuis said the fact that the 5 minutes feature is there is great but I would also love to get the option back to have the latest query always shown, not just within 5 minutes.
