ok, first of all don't me wrong, i've been liking OS4 on my 3GS. app switching is great, even when they cant really multitask yet, and folders have their uses. but i have a small pet hate, and i wonder if anyone else shares it. folders stay open when you close an app that is within one. so you have to tap the home button a second time or tap the screen to "minimize" the folder. anyone else find that a little frustrating? more often than not i dont want to open another app within that folder, so would rather that i have the click the folder again on the odd occasion i want to open something else. i mean, after all, if i wanted to switch apps i'd use the app switcher, right? i'm guessing there is no option for this since apple gives us very little customisation when it comes to this kind of thing?
