The one thing I would need to leave WordPress completely would be the ability to share a page/element/Preset I create between sites.
When working in Wordpress with Elementor, OptimizePress etc, etc. I’ll often create something on 1 website, and then want to use it on multiple others. This is doable with Most “Pagebuilders”, and is needed on SiteJet.
Hopefully this is addressed in the near future!
