‘Checklist Everywhere’ is a chrome extension that creates checkboxes on the website that you are browsing. It does not create a checklist everywhere. Instead, it will create checkbox at the end of each line that is specifically defined as
in HTML. When you tick off the checklist, the strikethrough will be added to that line to make sure you have read that line.
To create checklists, simply click on the extension icon on the top and click ‘Create Checkbox’ button. To remove, click ‘Remove Checkbox’ button.”
