To remove Elementor (free version) and the extra plugins I needed for my site, I was excited to see Gutenkit available on AppSumo. Unfortunately, it is riddled with bugs. For instance, every time I open the Editor, I have to save the Header and Footer again, even though nothing has changed. Modifying one of my custom patterns also repeatedly alters my Home page template. The latest issue - after an updated version of Gutenkit and its Pro plugins was released - is that, despite defining my picture sizes on the Home page, Gutenkit displays them in another size. I've managed to work around this behavior by reopening, redefining, and saving these patterns, templates, headers, and footers multiple times. It seems Gutenkit is not yet ready for Full Site Editing themes. It's a shame because the page speed improvements are quite impressive.
