Maybe I'm misunderstanding something, but one of my intended uses for content blocks was with very small bits of content and links. For instance, let's say I have an annual event that's referenced across articles and the sentence is: "Please plan to join us for the annual College Day events which will be held June 14-15, 2021."
When I try to insert a content block in the middle of a paragraph, it inserts it after the current paragraph as a new one.
