Task Coach is a simple open source todo manager to manage personal tasks and todo lists. It grew out of my frustration that well-known task managers, such as those provided with Outlook or Lotus Notes, do not provide facilities for composite tasks. Often, tasks and other things todo consist of several activities. Task Coach is designed to deal with composite tasks.

Features:

• Creating, editing, and deleting tasks and subtasks.
• Tasks have a subject, description, priority, start date, due date and a completion date.
• Tasks can be viewed as a list or as a tree.
• Tasks can be sorted by all task attributes, e.g. subject, budget, budget left, due date, etc.
• Several filters to e.g. hide completed tasks or view only tasks that are due today.
• Task status depends on its subtask and vice versa. E.g. if you mark the last uncompleted subtask as completed, the parent task is automatically marked as completed too.
• Tasks can be assigned to user-defined categories.
• Settings are persistent and saved automatically. The last opened file is loaded automatically when starting Task Coach.
• Track time spent on tasks. Tasks can have a budget. Time spent can be viewed by individual effort period, by day, by week, and by month.
• The Task Coach file format (.tsk) is XML.

What´s New in version 1.3.8:

Bugs fixed:

• Show a warning dialog when running XFCE4 to highlight the session management issues and tell the user about the option to disable it (3482752)
• Display times with a 12 hour clock (AM/PM) when the language is set to English (US).
• Don't change the selection when deleting or hiding items that are not selected. When adding a new item, select it. When adding a new sub item, also expand the parent item if necessary. (3484930)
• When using the Norsk translation on Linux (both Nynorsk and Bokmal), Task Coach would crash when displaying a date picker control. This is a bug in the underlying wxWidgets toolkit. Worked around by using another locale for dates and times when the language is Norsk. (1820497)
• On Mac OS X, the shortcut to email a task is now Shift-Cmd-M instead of Cmd-M (which is the system shortcut to minimize the active window). (3489341)
• Don't escape characters on Mac OS X when emailing a task. (3489341)

Features Added:

• In task viewers, late tasks, due soon tasks, and over due tasks can be hidden. It was already possible to hide inactive tasks, active tasks, and completed tasks. This makes it possible to create a task viewer that only shows e.g. due soon tasks or late tasks, or any combination of task statuses.
• Add an option to disable session management on GTK. The XFCE session manager causes Task Coach to hang randomly on start.
• On Mac OS X and Linux (with espeak installed), reminders can be spoken. This can be turned on in the preferences dialog, on the task reminder tab.
