[26.2+] Request: Restore iOS 18 app open/close animation speed tool - BookRestore method

iOS Version: iOS 26.2 / 26.3 beta Nugget Version: v5.1 / v6.0

Problem: On iOS 26.2+, Apple changed Liquid Glass again. The old "Disable Liquid Glass / Disable Solarium Fallback" tweak doesn't work anymore - it only removes glass texture but doesn't restore iOS 18 UI or animation timing.

On iOS 26, app open animation is 150ms faster than iOS 18 and zooms to 90% vs 50% on iOS 18, feels too aggressive. Reduce Motion is not ideal because it changes everything to fade.

I know MobileGestalt tweaks are not supported on 26.2+ anymore, but is it possible to add a new SpringBoard animation speed slider using the PosterBoard / SpringBoard plist method (like Batter files do for duration)?

Request:

1. Add support for iOS 26.2+ to adjust app open/close animation speed
2. Add slider: Animation Duration 0.3s - 1.0s
3. Option: Use iOS 18 animation curve (slow zoom) vs iOS 26 curve (fast bounce)

This would be the only way to get iOS 18 feel back on 26.2+ without jailbreak.

Thank you!
