  • emmetを利用できるプラグインで最も優れています

    テーマエディター上でemmetを利用したい目的から導入しました。emmetの利用はもちろん、豊富なオプションでカスタマイズ性も素晴らしいです。設定のUIも大変わかりやすいです。最終的に導入に至らなかった点は、テーマエディター上でファイル更新を行うと、ページが更新され元に戻せない点です。ページ更新やphpのエラーメッセージ表示・位置などがデフォルトの仕様であれば是非導入したいと思います。

  • I like it very much, but...

    Dear friend. You have made a wonderful plugin. I've wanted to find one for a long time and I'm very glad I found it. This is despite the fact that half of the plugin's functions do not work on my computer. Minimap, code folding, suggest function are absolutely dead. But there is a wonderful indentation system. Find and replace text works great. Code coloring is remarkably fast. Well chosen colors. Very convenient multiple selection and correction.Indeed, I have tried dozen of editors and coloring systems, no one of them is comparable to your package. Huge thanks to you for your work. Maybe you will find time to understand Why some of the functions do not work on my computer. I am working with WordPress 6.1.1, PHP 7.4.26 system. Even if you only make assumptions, I will be extremely grateful to you. I am Nick, best regards!

  • Wow Just Wow!

    <p>This plugin is solid. I LOVE it!Adds much-needed functionality to the Custom HTML block and then some.<br />Unbelievably well put together, you can tell the developer of this plugin has put much time and effort into its creation.<br />The options/settings available for the plugin are extensive and the little helper pop-up showing you visual representations of what the option does is really useful and intuitive.<br />The HTML custom extension also appears to remove wpAutop which is a filter which automatically adds to text. Which is great.<br />Your HTML formatting is retained! Yes, you heard right all your indents and extra lines etc, are not lost on save like the standard HTML editor.<br />Wow just Wow, congratulations to the Author of this plugin is very powerful, very useful and very well put together.<br />This plugin is an absolute must if you work with CustomHTML blocks at all!</p> <p>In the future would love to see this in use in the Code Editor mode (which for those who don't know is accessed via the visual editor with Ctrl+shift+alt+M)</p> <p>Thank you Aki Hamano! Hope this becomes core functionality in WordPress one day.</p>
