Hi @sendyhalim, nice work as always, using Yomu i came up with some feature: it would be nice if you add the possibility to change the background of the reader, maybe with a switch (grey and white), because some webtoon have white background and is confusing (at least for me). It would be nice if you could implement some key detection, like arrow and W,A,S,D, for navigate between page and chap. Eventually, for the next chap, when you scroll to the very last image, if you continue to scroll maybe load automatically the new chap..
