Is your feature request related to a problem? Please describe.

In todays busy world, everyone is busy more than they should be. So having a lot of tasks can make us forgetful and we easily forget what tasks we have completed or not completed.

Describe the solution you'd like.

My solution is to add completed tasks to local storage and then add to the DOM in To Do app so the user can easily see what tasks he has completed.

Describe alternatives you've considered.

There is a button on the page that, when clicked, displays the tasks you have completed sorted by date in newest to oldest order. Another button is available to clear the history of completed tasks if desired.
