WP Project Manager plugin lets you create to-do items within your projects. But what if you needed another thread of to-do items within your existing to-do? That's when you need the WP Project Manager Sub Task add-on.
What Sub Task does is it creates a second level of To-Do items within an existing to-do. You will have a Sub Task heading and an option to create sub tasks when the add-on is installed and enabled.
Sub Task is perfect if your project requires elaborated tasks to be assigned to yourself or your teammates/co-workers. Instead of creating too many To-Do items, you can create fewer to-do items with much broader list of tasks within each of those items by using Sub Task add-on.
