Notion Red Sheet is a Chrome extension designed to improve the usability of Notion by allowing users to manipulate the visibility of specific elements. This tool enables users to hide the "code" elements with a red sheet overlay, providing a streamlined view of their content. Users can toggle the visibility of these elements with a simple left-click, enhancing focus and reducing distractions.

Additionally, the extension features a right-click option that allows users to save memorization counts, which dynamically changes the background color based on the number of times a user has interacted with the content. It also includes a "print mode" display for those who prefer to memorize using physical copies. This extension is compatible with Notion’s web publishing URLs, making it a versatile tool for enhancing productivity and study efficiency.
