Apple really needs to develop an editor view for customizing home screens and Control Center. It’s so broken that the slightest movement can mess everything up in an instant. If they had a separate editor view, you can Apply it or Cancel it if you don’t like it and go back to what you had before.
Either develop this or fine-tune your current style of editing because I shouldn’t be afraid to add a widget to my Home Screen without messing up my current layout completely. LOL
