Totally agree.
Oversight by Apple to not have the feature to arrange the order of icons , especially as they’ve added more.
What I find is when I scroll up with my finger to activate silent mode , I accidentally touch another icon & switch it on. I know you can use the crown , but this is not the answer.
You’d of thought this feature would’ve appeared in 4.1 , but alas. Can’t see it happening now until about 4.2 , & that’s only if Apple see it as a problem.
