It does its job very well
by Marco Panichi·2 years ago
In the era of Gutenberg and visual builders, as a good old programmer of the past, I need to edit HTML code in the showcase pages of the WordPress sites I create. This plugin is therefore a must-have for me. It works very well, it doesn’t have many options but all those necessary to configure the editing environment comfortable for me.
The fantastically useful plugin

The fantastical plugin that converts faceless TinyMCE to the powerful tool.
The only suggestion is to mark dark/light themes, please
Works, even on iOS/mobile
by FolioVision·4 years ago
HESH is built on top of Code Mirror which is first class code. The implementation is somewhat eclectic including a settings button in the front end which allows the user to really play with editor settings. Easy access to the settings is convenient at first and then a bit of a distraction.
HESH even highlights WordPress shortcodes [shortcode] syntax.
What HESH doesn’t have is Markdown syntax highlighting in the posts/pages plain text editor but the WordPress shortcodes and HTML highlighting helps make up for it.
What is buggy are the settings on iPhone (iOS 13.5) where the settings buttons more or less don’t work and the settings can’t be closed. If you don’t touch the settings though, HESH provides a better plain text editor than WordPress default (which can be very finicky to accept text entry). It remains easier to edit on iOS with HESH installed than without so no downnmarks here.
All in all a great plugin, a bit overwhelmed right now with legacy support for WordPress 4.9 editor, Classic Editor, Code view, plain text editor, Gutenberg and the sixteen different kinds of blocks which might need syntax highlighting. I can’t blame the plugin authors for not being on top of all editors all the time now in the current Gutenberg-induced editor hell.
Very, very grateful for their hard work and looking forward to HESH v3.
