LeetCode Difficulty Hider

This Chrome extension hides the difficulty level of problems on LeetCode and provides a toggle button to enable or disable this functionality.

Demo

Features

• Hide/Show Difficulty: The extension automatically hides the difficulty levels of problems on LeetCode.
• Toggle Button: A popup button allows you to enable or disable the difficulty hider at any time.
• Persistent Settings: The extension remembers the last state (enabled/disabled) even after refreshing the page or closing the browser.
• Real-time Updates: Changes made via the popup button are applied in real-time on the current LeetCode tab.

Installation

1. Clone or Download the Repository

3. Click on the Load unpacked button and select the directory where you cloned/extracted the extension.

3. Using the Extension

• Once the extension is loaded, go to any problem page on LeetCode (e.g., https://leetcode.com/problems/split-linked-list-in-parts/description).

How It Works

• The extension hides the difficulty level elements on LeetCode by manipulating the DOM.
• It uses a combination of content scripts and Chrome Storage API to remember your preferences.
• MutationObserver ensures that dynamically loaded elements are correctly hidden.

Key Files

• manifest.json: Configuration file for the Chrome extension.
• content.js: The script that interacts with the LeetCode page to hide/show difficulty levels.
• popup.js: The script that handles the toggle button and updates the extension settings.
• popup.html: The HTML file for the popup UI.
• icons/: The folder containing the extension icon images in different sizes.

Future Enhancements

• Customize UI: Improve the popup design to make it more user-friendly.
• More Options: Add options to hide other elements on LeetCode (e.g., problem tags, solution votes).
• Dark Mode Support: Ensure the extension works seamlessly in both light and dark mode.
