Extendify also acquired one of my fav. Gut. plugins, the EditorsKit. It seems that unlike the previous owner, the new owners are unable to keep up with the Gutenberg updates. Pretty regularly, when things are working fine, and with a Gutenberg update the plugin falls apart. The EditorsKit plugin has many functions, so it's pretty complex. The new owner (Chris), like the old one, is very nice and willing to fix them, but it takes weeks (or longer) to fix the issues that keep arising from the Gutenberg updates, and when the fixes eventually come, are either insufficient or some ignored altogether. They merged their Templates library and a pretty useless Typography plugin into the EditorsKit plugin, which made it even "heavier" and thus added more places where problems would arise with future Gutenberg updates.

My real frustrations is really with the Gutenberg dev. team (and not Extendify) that constantly make breaking changes (why, WHY WHY???), where themes and plugins have to constantly adapt to things, with very little or non existent documentation. I'm sure Extendify is doing their best, but with their many acquisitions and what it seems their limited knowledge or lack of urgency made us dump the EditorsKit and EditorPlus plugins.
