> when you space out and need to figure out what's happening

Ok it's not just me that gets to the end of a page and it's like the page didn't exist.

On the other hand the times I use the search function on the ereader most are when I stumble across a continuity error. It would be interesting if a story-reading AI can be used to detect those. Not that I want there to be less human editing in books, if anything we seem to need more.
