Task Tracker Application

Build a simple command-line task tracker application using Textual that allows users to add tasks, view their task list, and quit the application.

Requirements

Create a terminal user interface application with the following features:

Application Structure

The application should have a title displayed at the top and accept keyboard commands to control its behavior.

Task Management

• Users should be able to add new tasks by pressing a key
• When adding a task, display an input field where users can type the task description
• After entering a task, it should be added to the visible list
• The application should display all tasks in a scrollable list

User Interface

• Show a clear title for the application
• Display a list area where tasks are shown
• Provide visual feedback for available keyboard commands
• Use appropriate styling to make the interface readable

Controls

Implement the following keyboard shortcuts:

• A key to add a new task (should open an input field)
• A key to quit the application
• The input field should accept text and submit on Enter key

Application Behavior

• The application should start with an empty task list
• Tasks should be displayed in the order they were added
• The application should handle the addition of multiple tasks
• The application should exit cleanly when the quit command is issued

Test Cases

• Starting the application displays the title and an empty task list @test
• Pressing the add task key displays an input field @test
• Submitting a task through the input field adds it to the task list @test
• Multiple tasks can be added sequentially and all appear in the list @test

Implementation
