Issue: Without another tweak like FolderController14 scaling the icons, they get really tiny in landscape mode. Also the widgets can tend to rotate a little weird, but that could be a fix for FolderController.... Anyways,
I've found a few neat methods for iOS 14, one that I believe will allow FaceID to work sideways. I've got my 12 Pro Max working almost perfectly like a mini iPad, just have a few things to freshen up and test, and then decide if I want to expand compatibility for 2 row dock tweaks as well as make it so you don't need the icon scale options, which are separate for landscape and portrait, in order to use AutoRotate on iOS 14.
I think I'll just find a common scale that seems good, along with adjusted dock height and status bar for landscape.. been working on this behind the scenes will hopefully have some new code up and an update soon.
