* Prepare for edge-to-edge MangaController * Fix derpy liftToScroll with our own implementation * Edge-to-edge MangaController Except when legacy blue theme is used. * Save app bar lift state for controller backstack * Fix expanded cover position after the view recycled * Handle overlap changes when incognito mode disabled * Tablet fixes * Revert "Handle overlap changes when incognito mode disabled" This reverts commit 1f492449 Breaks on rotation changes. * Fix MangaController's swipe refresh position * All controllers are now doing lift app bar on scroll by default They are already doing that before so this pretty much just a cleanups. * TachiyomiCoordinatorLayout: Support ViewPager for app bar lift state check I'm willing to revert this if this minute detail solution is deemed too hacky xD * Fix app bar not lifted when scrolled without fling * Save app bar lift state across configuration changes * Fix MangaController's swipe refresh position after configuration change * TachiyomiCoordinatorLayout: Update ViewPager reference when controller is changed
