In reply to Nick.

I think the OP is probably more interested in using it as a content editor as opposed to a page builder, at least based on what he said. Classic editor is not cut out to be a page builder either. I find the block editor to be a superior content editor.

The block editor feels light years away from being a true page builder at this point. I think we'd agree on some of the things that need to happen in the more immediate future.

Right now, full-width and wide-width theme support does not handle near enough max-width use cases. I also dislike that they are grouped with alignment classes. In design, I typically have a larger range of max-width classes. The current system needs to be re-thought.

Padding and margin classes need to be available for themes to opt into. Currently, users are stuck with faux margin/padding using the spacer block, which is based on set pixels instead of theme-defined sizes. That's one of the most irritating things to me right now.
