Take a look at this project. Xslar it's not only a task manager but also a habits manager. First, it allows you to create your project and divide it into multiple tasks over the days. Moreover, each task has subtasks. You can drag and drop these tasks on multiple stages, such as "to do", "doing", and "done", for a better organization of the tasks!
Also, the habit section allows the user to manage their repetitive habits throughout the entire days of the week. This feature is great if you want to build habits.
You can take a look at it now, or just support it if you want!
