Add Work in Progress Checkbox

[sohang3112]

Proposal

Currently 2 types of checkboxes are supported:

• [ ]: Unchecked
• [x]: Checked

Support a third type of checkbox: [-] for Work in Progress / Partially Done. It would be especially helpful when maintaining a task list in a Markdown file.

This can be implemented by setting .indeterminate property in JavaScript:

let checkbox = document.getElementById('my-checkbox');
checkbox.indeterminate = true;
