fix: remove not working for multiple elements

document.addEventListener('DOMContentLoaded', function() {

	class ListNode {

		constructor(data) {

			this.data = data

			this.next = null

		}

	}

	let head = null

	const contents = document.getElementById('app-content').lastChild.children

	for (let index = 0; index < contents.length; index++) {

		const content = contents[index]

		const contentHeaderText = content.firstChild.innerHTML

		if (contentHeaderText.includes('Keyboard shortcuts') || contentHeaderText.includes('Navigation bar settings')) {

			content.remove()

			const tempHead = head

			let node = new ListNode(content)

			if (head == null) {

				head = node

			} else {

				node.next = head

				head = node

			}

		}

	}

	while(head != null) {

		let node = head

		head = node.next

		node.data.remove()

	}

})
