His point is that while you may see no use for such a feature, it doesn't mean others don't. You should have the ability to understand this. For example, I listed an example where a person may need to switch between apps from page 4 to 10 quickly. This is where this feature comes in handy. My reply was met with "Well why don't you just put it in the same folder?" While that's doable, not everyone wants to do things like you.
Exactly, thank you.
I know what he's saying, I'm just saying that those are 2 entirely different scenarios. And all I did was give you a third option in your scenario that does much the same thing as the "multitasking bar" which currently is more of a recent-apps-which-may-or-may-not-be-multitasking bar.
The multitasking/recently-opened-apps toolbar is a convenience for those who use it. If you don't find it practical, no one is forcing you to use it.
Also, for those looking to add functionality to the multitasking feature, try "backgrounder" from cydia - you can keep any apps you want running in the background.
