Sounds like a useful idea to me.
You probably know that it is possible to arrange the app icons manually by dragging them to any order. In addition, one can create folders, name them and select different colours and shapes for the folders. Now, app icons can be dragged to those folders. This makes it possible to have tens of apps in one view and opened with two taps.
This rearrangement is started by long-tapping at the app grid.
I have about 45 apps in this view.
