I went through an unintended restore and lost a tweak I know exist.
What it did was basically enhancing the original functions of the “Portrait Orientation Lock” control center button, and added the function to also lock in landscape.
Very simple tweak, and worked better than any other predictive work around sto achieve the same.
It worked on iOS 14.3, but may have been developed earlier, and never officially tested for this version of iOS. Therefore, any tweaks that do this marked for earlier versions of the OS would be welcome.
