LeetCode Mate Extension

LeetCode Mate is a Chrome extension to improve your LeetCode Experience!

The current LeetCode UI can sometimes be hard to use when running custom user input and read debug print information using the left hand size panel. The output box is too small to read out useful information without scrolling.

This extension addresses this issue by creating alternative resizable, and draggable dialog panel for run and submit code and display their run results accordingly. User can also toggle the UI of the extension by a keyboard shortcut.

It also supports Toggling cursor blinking and bracket matching for the CodeMirror Editor.

Both LeetCode-CN and LeetCode are supported.
