I really love this app I thank you so much for making it! I have but one inquiry for some reason recently whenever I try to add a zip file manga it shows up as a damaged file. In the past I had no trouble creating zip files and then viewing them here so maybe something with the update? Otherwise I really love the app 🥰. Also is there any way you can add a feature to edit and draw on files? Like highlight and underline and stuff maybe 😁

The more I use ,the more I like. I found a easier way to add pdf to sidebook is after downloading a PDF,click open, then choose sidebook app. Then it's automatically added. Otherwise need to manually add each pdf using a file manager app. Place pdf in correct location for sidebook to recognize.Otherwise, I like the page effects, also can trim pages to fit better, draw or underline words, bookmark a page,switch magazine quick.etc. great app 👍

I've been using this app for about 2 years and to call it a good pdf reader would be an understatement. But there are two main issues I have: on my Samsung A71, android 13, I keep getting crashes whenever I open a second pdf. I'd also like forced dark mode to be potentially implemented
