Yeah, it was vaguely seeing things like you mentioned that makes me apprehensive like automatically making major interface changes or maybe it asks you if you want to do certain things right after the install and you're not entirely sure what it means. I heard something about it having the option for it to automatically put apps in folders.
Yes they do now sort out aliases of all your apps into a sort of phantom page to the right of all the pages you created yourself. It represents your downloaded apps library and has folders of their own categorization. Plus a search bar at top with 'App Library' indicated in it. The other regular search bar is still in the widgets page to the left of your own pages.
The new apps library page is especially weird if you've grouped your apps into folders you created as desired, and so have those folders wherever you want in your own pages. I just try now not to thumb my way to the right of my last page of apps, which holds items I rarely use anyway.
Just not sure why Apple did this. Do people not get it they can make folders for their apps by just holding one app over another and put them wherever desired?
Plus I just don't get some of their categorizations. They stuck my Shakespeare reader in with iTunes University. I have that app in with my other reading apps like Libby, Books, Kindle. They put those (and Mactracker no less) into a folder called Information and Reading. OK then...
They stuck my two Bittman's recipe apps in with shopping, and I never go shopping off a recipe lookup: au contraire, I'm in recipe apps when I'm trying to figure out how to use up what I've already got on hand.
The weirdest one was putting my password manager in with Notes, Mail, Keynote, Reminders, Numbers, Pages, Calendar, PDFReader, Contacts and Files and calling it "Productivity and Finance". Wut? LIke I might ever get productive trying to fish through all that looking for anything. My password manager lives in the dock, and I'd never think to stick Numbers in with Contacts.
Oh well. Looking over Apple's vision of how to sort out apps was interesting anyway. Sort of like spying on how exactly the proverbial committee of blind men would design an elephant. They don't know exactly how we use our apps, or how often and in what combination. Maybe the library they offer is useful to some iOS device owners. And maybe they should offer not to create it for the rest of us...
