To-Do List: Challenges

Complete the following challenges building from the existing to-do list application. These challenges will require some additional research about C# Lists.

Clear list command

Add a command to the application that allows the user to clear the entire to-do list.

Order items

When viewing the list, display numbers instead of dashes, like so:

1. Item One
2. Item Two
3. Item Three

Remove items

Add a command to the application that allows the user to remove items from the to-do list.

Reorder items

Add a command to the application that allows the user to reorder the existing items in the list.

High importance items

Allow the user to specify whether or not an item is of high importance. When the user views the list, print the high importance items in red.

Storing/loading items in a text file

When exiting the program, store the to-do list in a text file. When opening the program, load the existing to-do list from the same text file.
