Nice. Given that in the previous step, what used to be called display got renamed to display_buffer (I think "buffer" ought to be sufficient in this context, though), the variable of "struct display_state" type should NOT be named "display", as it would be confusing when two things are related to "display" and only one of them is called as such. Either "display_state" or "state" would be fine. Thanks.
