Reusable Blocks in WordPress

But one of the best features of the new WordPress editor is my focus today: reusable content blocks.
I really can’t think of a feature I was more wrong about in WordPress recently.
In a new post or page where you’d like to access your reusable block, you’ll start by clicking the “+” (plus) button anywhere, ideally in the gap where you’d like your reusable block to appear.
