The space between pages isn't actual a vertical bar - it's just black/empty space. When the overlay is visible, the pages become smaller, which just increases the amount of empty space between them due to their height shrinking. Having said that, I can certainly put a vertical line between the pages to indicate when the left page is ahead of the right page. Other users have suggested a different background color or a border around the entire page. It would really great if users could provide their feedback on the method they prefer so I can choose the most popular solution. A colored vertical bar is certainly the simplest solution, meaning it can be implemented the fastest. Another question is whether this should be something that should be configurable vs just making it a normal part of the alternage page turn mode.

Thanks,
