The really critical issue for me with FE is that the blue + "insertion points" available in the classic editor are gone in FE. This means there's no way to insert images or other blocks on the same "layer" as text and then to flow the text around them. This seems like a huge oversight, and makes design much, much more difficult. It's a shame, as the regular, classic editor (still usable on blog posts) is fast and intuitive, and it feels like FE is a step back from that.
