One of the standout features of Hey World Code Blocks Enhancer is its ability to highlight code for better readability. With both dark and light themes available, users can customize the appearance of code blocks to suit their preferences. Additionally, the extension remembers your selection, so you don't have to manually apply the theme every time you visit a code block.

Another useful feature is the one-click function to copy code snippets directly from the webpage. This saves time and effort by eliminating the need to manually select and copy code. With just a single click, users can quickly copy code snippets and paste them into their own projects or documents.
