An iOS 11 targeted tweak to round corners in card/ deck switcher, screen edges inside Apps, Control Center modules, sliders and buttons, Notifications, Widgets, and more. Latest update only compatible iOS 10-11.x, screen rounding only iOS 11, all other features work on iOS 10. Note: if on iOS 10 must have XZ utils from Bingner repo for package to install correctly.
Tested on 8+ 11.3.1 and 6s+ 11.1.2
Changed settings to user defaults and added arc; settings all update instantly now, respring only needed for Round/ Square UI slider. Also got rid of bug causing the occasional need for 2 resprings with the Round and Square custom UI setting changes.
