Homework Rubric: 47/50 total

Nice job Taylor! Review your comments here and then close this PR when you're done.

Functionality: 29/30

Completion: 20/20

• 20 - You implemented all of the required features in the assignment. The assignment is complete
• 15 - All major features were implemented. You didn't get to one or two small features.
• 10 - Some of the required features were implemented.
• 5 - An attempt was made to implement some of the of the desired features.
• 0 - Very few or none of the desired features were implemented.

Bug free: 9/10

• 10 - The app is bug free
• 5 - Your app has one or two bugs, occasionally causing unexpected behavior
  Not really a bug, but you have an interesting functionality where in order to edit, the user has to double-click on an item. But single-clicking on an item toggles its completeness, so it toggles and then I assume toggles back after your second click.

Quality: 18/20

See my in-line comments in your code.

Good coding practices: 9/10

• 10 - Follow good naming conventions, use triple equals, use indents and whitespace where appropriate, know when to use global or local variables, etc.
• 5 - Some of the above practices were broken, but you mostly followed good practices.
• 0 - Good coding practices were consistently broken.

Readability: 9/10

• 10 - Functions and variables are named well. Code is well commented where appropriate. Confusing lines are commented. Lines are not too long.
• 5 - Code is occasionally confusing. Could use more comments. Some variables are poorly named.
