Here is my idea. It would be a modification to the springboard that allowed for apps to be hidden. I am not talking about going into SBSettings and using poof to hide an app. I am thinking something along the lines of this: You hold an app until they all wiggle. On the right hand corner of the app a minus icon appears (similar to the x for deleting apps). when clicked this will hide the app. To unhide you would probobly have to open SBSettings. To be a good mod, this would have to be able to hide the app without respringing. I do not know if this is possible, but as I see apps like PogoPlank and Stacks v3 A2 come out I believe it is drawing nearer and nearer. One thing I noticed specifically about Stacks v3 A2 is that it can change the icon of the stack without requiring a respring.
