DevPlanner since v2.1 includes possibility to track mood state changes in real time. The main goal of mood tracking is possibility to build moods map. This map allows visually identify dependency and repetitions of specific emotional state in time. For example, almost every Monday morning I'm fresh and enthusiastic. This time seems the best for accruing interesting ideas and learning.
Process of tracking emotional state with DevPlanner is quite simple. After two days of practice it performed almost automatically. On the Mood tracking pane, usually right most, there is a list of emotional states with appropriate colors. Initially this list is populated with a standard mood and color associations what taken from Psychology books.
Of course, this list can be modified with personal colors association.
Moods map for a week can be built using DevPlanner report of the same name. This report represents daily mood changes in colors.
