## Overview

This is a command-line to-do list manager organized around dated lists and the tasks stored in them. A user chooses a list operation, then can create, remove, or open a list; within an open list, they can add, remove, or edit tasks. The application loads and saves manager state through a local text file. The README is empty, and Task and TaskList implementations were not sampled, so their internal behavior and some dependencies are not detailed here.

Main entry points: [`taskmanager/src/core/TaskManagerApp.cpp`](https://github.com/loganoberk/taskmanager/blob/main/taskmanager/src/core/TaskManagerApp.cpp) (Application loop), [`taskmanager/src/ui/UI.cpp`](https://github.com/loganoberk/taskmanager/blob/main/taskmanager/src/ui/UI.cpp) (Menus and input), [`taskmanager/src/core/TaskListManager.cpp`](https://github.com/loganoberk/taskmanager/blob/main/taskmanager/src/core/TaskListManager.cpp) (List manager), [`taskmanager/src/core/TaskList.cpp`](https://github.com/loganoberk/taskmanager/blob/main/taskmanager/src/core/TaskList.cpp) (Dated task list)
