Hi @karmatosed,
sorry for the delay,
I think the concept of using a javascript framework like React has been a great decision and in the end will outrace other visual editors in the long run.
Also, I like that Guttenberg is using HTML comments instead of the shortcodes, this helps other plugins like Yoast (SEO) to read content more clearly and give you proper recommendations.
Another one is the fact that you can use the editor on both posts and pages is great too! Other editors can allow you to edit posts, but it’s much more troublesome to strip shortcodes out from the content than it is removing HTML comments. (Yes, excerpt should be specified for such cases, but a lot of people (authors, editors) just like to omit it.
From what I would love to see is:
more advanced columns control – with the 5.3 we now can have uneven columns and that is great, I would love to see the ability to control paddings/margins for each side, backgrounds (color, gradient, video) – those are what makes other visual editors so powerful. It is possible to add a class, but that is unfortunately not the same.
Thank you,
Max
