WorkHourGlass is a simple timer that allows you to manage easily your
working time. It times your work and breaks, making a beep sound at the
end of each so that you know you can take a break / return to your work.
There is also a change of color between break time and work time. Moreover, the times, sound and colors are customizable.

etm is an acronym for event and task manager. In contrast to most calendar/todo applications, creating items (events, tasks, and so forth) in etm does not require filling out fields in a form. Instead, items are created as free-form text entries using a simple, intuitive format and stored in plain text files. Both a graphic user interface based on Tkinter and a command line interface are provided.
