td is a graph-based TUI todo app. It allows you to create tasks and define dependency relationships between them. This way you can see which tasks can be worked on right now, and which tasks still have unfinished prerequisite tasks.

td is still in development and while basic functionality is present, it is still very unpolished (it is not v0.1 yet). See todo.json (or open it in td!) to see some of the remaining tasks.
