It was mainly for an exercise to get familiar with sqlite. Maybe later very rarely I can use the session data (hunting down sessions where you only remember some irrelevant command). Getting the duration of some commands is useful like long running simulations, compilations. It&#x27;s especially handy where you don&#x27;t expect it to be too long and forget to time it beforehand.<p>Having said that I didn&#x27;t use it too much yet, I have my regular history in place too.
