I am not confident he will. It's weird, some of his tweaks he keeps up to date with necessary and regular updates. But then other tweaks rarely, if ever, get updated. DietBar is one of my favorite tweaks from him because I love the additional real estate. It doesn't seem like much but when you go back to stock and navigate your frequently used apps, you realize how unnecessarily big navigation bars are when stock haha.
I use this tweak as a reference because it could use an update. Many apps have tiny graphical issues in and immediately below the navigation bar. It's been like that since he released it during Tweak Week.
Maybe FullScroll will different. Maybe it won't. Im just adding some context to the thread. Personally I hope he updates it to address all these concerns in this thread. It has great potential but for me, I can't use it right now. It really doesn't play well with DietBar at all. Nonetheless, I changed the package settings for this tweak in Cydia so I'll be notified if/when it gets updated. I sure hope so! I am a huge Petrich fan
