I think it's a problem if I've got 30 apps clogging up my multitasking switcher.
What's the point of every app you've ever opened staying there forever? It's messy.
It's like I said earlier... if I use an app briefly in the morning... why does it need to stay there all day? It doesn't... I close it when I'm done with it. I don't want to see it until I need it again.
Or maybe you use the Costco app once a month. Do you really need it open for the rest of the month? Also nope.
I understand the point of the multitasking switcher... it's to switch between a couple or a few tasks at the moment.
It's not a replacement for every app icon in Springboard.
Otherwise... why not get rid of app icons altogether... and just put every app in the multitasking carousel? And scroll until you find it?
