I appreciate the feature is a nice one, that the wifi will turn back on sometimes. I've been caught out. But I can't know what hidden features exist and how to distinguish them.
Moreover, "Disconnected from WifiNetwork" only communicates what you say it does once you know what the feature does. Until then, you don't know. There's also nothing that says "the network has been disabled until you go home" or whenever it's going to turn back on.
Apple used to care about their products being useful to power uses and beginners alike. Now they care about their products being useful to beginners and capable of letting the elite know who they are — the power users who are not amongst the elite know that too. It's really not very nice.
I was really happy with it when I first got my iPhone. It was awesome. I'd never used one, and it kept telling me what to do next. If I guessed wrong, it was like "haha, no you've gotta do this instead". But it is not going to be replaced with another iPhone. I just can't stand it any more.
Maybe a lighter shade of blue? Or a white background with the icon colored vivid blue?
Seems fine for me /shrug
