There was a bug where the readability analysis didn't give you a checkmark if you used undo to get back to the state of the drawing before you opened the analysis paper. I've changed the logic now a bit so that the analysis always computes in the background and it only shows after you first open the paper (so it doesn't distract you when you're initially drawing).
