Installing this plugin you will be provided field tested code snippets to enhance your website. These code particles include lightweight security tweaks, cleaning functions and other useful elements. Please note however, that Useful Snippets is not a security plugin––most of securitiy enhancements should be made on server level.
Following snippets are available: 
* Setting up security headers. 
* Disabling XML-RPC. 
* Unhook the Core function that adds the inner container to blocks.
Following cleaning enhancements are available: 
* Removing WordPress default SVGs.

Line Numbers + Line Highlight Not Working


Thank you for contributing this plugin. I went looking for a good option when I noticed the previous one I was using was not working well in Gutenberg. I have been using Prismatic for the last three years without issue.
