< Feedback on NHentai Improved
Infinite scroll is working on my phone just fine using Kiwi Browser + Violentmonkey. The script is developed mainly with desktop in mind and I only "recently" ensured it mostly works on phones, but haven't tested it widely at all.
What browser are you using and how are you running the userscript?
HQ only determines if the thumbnails get replaced with higher resolution images. To adjust the visual size of the images, set "Thumbnail Width" to what you wish under "Comic Pages Section Settings"
The script is developed assuming you are logged in. I know this isn't great, but it's one of those things where I initially just wanted to do some small improvements for myself and I'm always logged in. Then the script got larger and here we are. I think most of the features should work with you not logged in, but I can't guarantee it.
All this being said, I'll try find time to test and fix potential issue regarding a better phone / logged-out user experience at some point... (including moving the settings outside of the profile page)
Update:
So there was actually an issue with infinite scroll that caused it to break on pages other than the home page. It happened on all platforms, not just phones.
That should be fixed now.
Infinite scroll doesn't work on phones. And why does the manga page now only show one thumbnail per row? I have removed the HQ and it still happens. Can you set the script setting and blocked tags to be outside the profile, like the subscriptions? I don't want to login every time I use the web. Thanks!
