Maker vs Manager

This extension looks at your weekly schedule in Google Calendar and computes whether you have a "maker schedule" or a "manager". The scores range from 0% to 100%. A higher score is more of a maker's schedule while a lower score is more of a manager's schedule. The extension looks at the number of meetings, the time of those meetings and the free time in your schedule to compute the score.
