Any good Pixiv tweaks for iOS?

I’m looking for a good Pixiv tweak/tweaked IPA for iOS, preferably one that keeps the official Pixiv app/UI rather than using a completely different third-party client.
The main features I’m looking for are:
- Completely remove ads, including the bottom banner/ad space
- Sort search results by popularity/quality without Pixiv Premium
- Keep the original Pixiv UI and normal account features
- Ideally compatible with recent versions of Pixiv/iOS
Sideloadable without jailbreak
Downloading original-quality images would also be nice, but it’s not essential.
Does anything like this currently exist? I’m fine with injecting a tweak into a decrypted official Pixiv IPA myself if there’s a maintained tweak available.
Thanks!
