I tried it with the Gutenberg plugin – it does not work with it 🙁
It works also if Gutenberg ist active, but only on the classic mode on each box.
see https://github.com/bueltge/AddQuicktag/issues/45#issuecomment-436411458
For now it works not on the Gutenberg UI, Editor – however why, what is the benefit to enhance AddQuicktag for Gutenberg. Lot of functions from AddQuicktag are a core feature in Gutenberg, like custom areas, reusable.
Thank you for your answer!
I really like your plugin and have created hundreds of quitcktags. I have difficulities working with Gutenberg. So with your plugin and the classic mode I feel quite comfortable 😉
I have also lots of Quicktags … shortcodes for theme specific things, text snippets etc.
None of these things how we use AddQuicktag is a part of Gutenberg. AddQuicktag is for very individual snippets of texts, shortcodes etc.
Please read this issue on the dev repo, maybe this helps you for the next steps.
