Style the Checklist Widget
To pick out a Theme for your Checklist, go to 'Widget'. You can pick out either a 'Light' or 'Dark' Theme. You also have the option to create your own theme.
The 'Widget' gives you the option to add an Icon to your checklist, or uploading and adding your own.
Next, it's time to pick out your Text Font and Color. You can even add your own font!
And finally, the 'Close Button'. This feature is optional, but if you do activate it, it gives you the option of either minimizing or dismissing your Checklist.
