I meant the "Better Way", 1 step for quiting, not 3 steps to quit an app.
Mine still stay, it didn't delete the folders after syncing the apps.
There is definately A REASON to "KILL" the app with a simple/quick way just like the current OS3.1 if you don't want someone to look at your apps "HISTORY" that you've been running. The multitasking dock holds the all the apps that you've been executed if you just press home button 1 time as you do on the current OS3.1.
I am not concerning about the battery life caused by the multitasking, but I am just concerning the privacy that the dock shows all the apps that I've executed if I woudn't quit the app with a proper way.
Try to run apps as many as you can, then just simply press the home button on the each app as you do on OS3.1, Now, you will notice that all the app icons you've executed will be shown on the dock even though it doesn't support the multitasking.
Let say, your mother(or co-worker whatever) asks you to show some photos on your phone when you write some SMS. While your mother's watching your phone screen, you press the home button twice to switch the app, BUT in the dock, "THERE IS KAMASUTRA ICON" that you thought to quit completely last night as you did on OS3.1 (One time Home button pressed). What a shameful! if you didn't quit it with the proper way (3 steps)
Again, the problem is that OS4 beta's dock holds all the app icons you've been running, no matter whether it supports the multitasking, it also acts as "Recent Items in Mac OS X" if you didn't quit the app with a proper way
Conclusion? it should be added "Kill ALL" function just like the WM, and the Option for home button to Kill or make it background. Additionaly, "Kill only paused apps" will be nice.
