Instead of remaining record time display, there could be a time tracker to show how long we've been working on our projects. This time tracker can pause if we don't click for 3 minutes and go afk. So we can know for sure how much time does the project consumes, this way, we can optimize our efficiency and predict when we are gonna finish the current projects.
Also, for people who work by the hour for their clients can show how much they've worked.
