I hope to use it for life

The options in the sidebar are really good; the themes are awesome. At first, I just wanted to find a plugin to help extend the default Gutenberg code block. But when I tried your plugin, I accepted using a non-default Gutenberg block.
What I worry about the most is that if one day you no longer maintain it and the plugin is accidentally incompatible with the new version of WordPress, it will be miserable for people like me who like to share code.
So I hope you never abandon it.
Thank you very much.
