Great tool for on the fly theme.json editing too.

Looking for a nice-looking editor for making quick changes to theme.json? Look no further. Should you edit source files directly? Well, on a test or developing site you should be ok. Also, it looks like corrupted settings in theme.json won’t break your site; it’s just being ignored. WPIDE features syntax highlighting, search and replace, full-screen editing and more. And did I mention it is really pretty?
