Would it be possible to add a setting to adjust the spacing between pages? I'm on iOS and the small spacing between the pages for Webtoon is a minor annoyance.

Piggy-backing off of another thread ("A gap (vertical strip) in double page mode"), I think a setting to adjust rather than a fixed gap would be preferable here too since I'd hate for a two-page spread to be separated by a blank space. E.g.:

For webtoon I recommend enabling the continuous vertical scroll mode.

I will think about the feature. Thanks for the suggestion.
