Lock screen is not broken for me. Can you be more specific?
Control center is quirky... can you be more specific? Seems to work as intended every time I pull it down.
Gigantic headers, can you be more specific? If you're on an iPhone X, you need room for gestures at the top and bottom of the screen to pull down lock center, control center, swipe up to home or swipe between apps. To me, they make a lot of sense. Can you explain yourself a bit more?
Music App - I use it on a daily basis, with a few qualms over how search is handled, specifically. Can you be more specific with why you think the music app is trash?
Folders being glitchy... again, mine work they way they're supposed to. Can you be more specific?
Widget center is laggy... yeah, I do wish that they widgets would be loaded by the time I swiped over. Thanks for bring specific on that one.
