Changes Made: Much of the code has been rewritten . Latest Page and Search Functionality Updates. Filters added.

Question: I didn't have any problems while testing when I updated the AndroidManifest.xml file, but could there be problems when updating from source? Can you confirm this?

Such a big rewrite doesn't make sense. Too much copied from MangaThemesia template to this totally unrelated website, making it hard to review.

Thank you for feedback. UzayManga was completely unusable in its current state, so I wanted to update it. Since this was my first PR (and my first time using Kotlin :D), I thought it would make sense to base it on a properly working file (turns out I was wrong). However, most of the code really does contain site-specific implementations, with only a very small portion preserved from MangaThemesia. If you could provide some guidance, I’d be happy to complete the improvements. What approach would you recommend?

If you are curious code is the same that ElderManga. manga-download/haruneko#1333
