todo is a GUI task management utility that does one job, which is managing & storing your tasks. The app is written completly in C in under 1000 lines of code.
It supports serialization & deserialization of tasks. Furthmore, the app implements a priority system for your tasks and the displayed tasks are sorted from high to low priority. There is also a filtering system that filters tasks after different critia (eg. completed, high priority,in progress).
The application is designed with configuration in mind and editing the config.h file will let you configure everything very easily. The source code is also very extensible and it is easy to add or change features if you have some knowledge of C.
The UI of the applicaton is written entirely with the leif UI library which is a small immediate mode UI framework that i've written. The rendering is done with modern OpenGL by utilising a batch rendering system under the hood. As todo using any big UI framework like QT or GTK, it can be considered as very suckless.
todo can also be used in the terminal without any gui if you prefer that. There are subcommands for every action that can be done in the UI. For more information:

./setup.shOn Windows:
You would need to manually create a build script for leif and build a static library and then link that library with the todo app and compile the app. That would be a bit of a challange, but possible :)
