Just a heads up for screenshotting webtoons; you can do it if you load it up in your browser instead.
That being said, for ongoing series, I use the Mihon/tachiyomi webtoons extension, and if I can't read a series because its locked the mangasee extension rehosts everything the moment it is free (and usually the last few chapters are free for at least a little bit before their shit paywall goes up).
My biggest issue with webtoons is that basically no translation group will touch a series hosted there, and that webtoons doesn't hire skilled translators/typesetters, so it always feels like I am reading a fan translation.
Probably, but I haven't used nova launcher since it was purchased by an ad company.
