A simple FileHandler which provides an easy way to keep a diary of categorized task activities.

Categories have a simple description and can be organized in a hierarchical manner. Each category then contains one or several timespans when it is active, which is termed an activity.

Selecting a category in the hierarchy will display a quick summary of the time spent in all its activities (and those of its children). It also features a customizable calendar-like graphical display of those activities which provides a visual feedback of the “activity” of a category.

A simple reporting is also integrated, which can be customized very flexibly via setting of application variables.

As this FileHandler supports modification and saving of the loaded data, it is an editor by nature.
