I'm sure it's a simple task, but at what point do you stop, that is why I asked how many you would like to see in a folder, 24, 48, 72 ? At some point you have to decide to stop. When you have to scroll is that a stopping point to make a new folder?
Yeah that is true... I personally do not mind scrolling which is why I assume they stopped with 12 apps because it makes it so there is no scrolling. To answer your question I haven't run into a case where I need more than 24 apps in a folder but I figure that depends person to person.
