Listen, the editor looks awesome but IT IS INCREDIBLY SLUGGISH!
I recently created a very big post, around 4000 words, with images and image galleries, and everything is slow when working with it:
– selecting text
– adding new blocks
– formatting the text
My WP version: 4.9.8
Browser I tested in: Firefox Quantum 63.0.3
Macbook Pro Retina mid-2014
