I think the most annoying iOS 11 multitasking behavior is how the slide over behavior works when combined with non-multitasking capable apps... especially when “returning” to an app. For ease of comprehension let me explain what just happened to me (and I’ve had countless other examples of this over the past year). 1) the most recent slide over app was safari (From last night when I was doing some minor safari searches over a YouTube video) 2) Today (over 12 hours later), I’m browsing safari in full screen mode and click on an amazon link 3) This bumps me out of safari into the full screen amazon app 4) I finish looking at the product and attempt to return to safari (either by clicking top left area, cmd+tab, 4 finger swipe) 5) The little slide-over safari pops up (since it’s still retained in that mode from yesterday) 6) Grrr.. kind of annoying but let me just pull on the grabber to make it a side by side app which I can just pull accross to full screen.... oh wait amazon doesn’t allow side by side apps... ok lemme click on safari from the quick access dock area... hmmm... just brings the same slide over... uhhh uhh... why is life so hard?? 7) brain explodes Note: the same thing happens when clicking on a notification from an app that’s saved in slide over mode. Now I know the “solution” is to simply go “home” and then reopen safari, but it’s such a frustrating experience. I don’t know if the answer is to require all apps have multitasking ability (obviously not tenable for games) or the slimplest thing would be just to encorporate a gesture on the grabby bar (either double tap or long hold) to full screen the app.
