@Seth The app is really good. Can you support the webtoon mode reader?  It should be vertical scroll continuous. Tachiyomi has webtoon mode, but it doesn't support Ubooquity. I want this feature because many webtoon comics have really big image in height. It's really inconvenient to read comic now when I have to zoom in the image then scroll down to read the whole image.

Did you go to admin page and check "Enable OPDS feed" ?

"A kind of "safe for kid" flag (ok, i have already asked for it and you refused, but i dont find a way to manage folder properly for my little nephew :( ... and personnaly i'd like to access to my complete library without asking to myself if i'll read an adult or a kid book)"

You go to admin page and in 'Security' tab check 'Protect shared content ...'. Then click 'Add User' to create one account for adult and one for kid.

Then create two folders of comics: one for adult and one for kid. Then set permission in 'Comics' tab for which account to access these folders.
