I just purchased the app and set up the Server, it's working great so far! I have one minor question about vertical scrolling mode. I know it's intended for webtoons but I like to use it for manga on the iPhone. Is there an option anywhere to add a very small "padding" (like a black bar) between pages to separate them? Since manga is not intended to be seamlessly connected, it would be nice to have a subtle visual indicator of where each page begins and ends. This is just a minor question...overall I really like the app!

No, there is no way of doing that. I will keep it in mind.

I am glad to hear you like the app
