That's the ideal! The problem with time tracking is that the hours don't get captured in the first place. Automatic tracking greatly increases the likelihood that the time is captured. We'll do more to automate in the future. Our current focus on that front is integration with accounting systems as those tend to be a costly part of the process to the business (either time lost or money spent paying a bookkeeper).
Huge fan of Wakatime here as well -- I usually work on more than one project simultaneously and it helps greatly that Wakatime tells me exactly how I've split my time between each repo.
