I just updated to version 4 (4.0.5) of SP Page Builder, and I have integrated it into Joomla Articles (in version 3 of SP Page Builder).
In version 3 of SP Page Builder, it allowed me to edit the structure of the elements (I could see each block, give it a name, and edit the corresponding items in the back-office). The new version makes me edit everything in a preview version of the page, but that doesn't work for me, because first it doesn't allow me to edit anything (maybe a z-index clash with some item?, and also it doesn't show any way to view the names of the sections, etc.
How can I have the same behaviour that I had in version 3?
