Genius. If icons are too small, we could have them large, maybe 3 (launcher default) or 4(most people's preference) across and scroll to the right to get the rest. And you could tap+hold to move them around, just like the rest of the launcher.
On the touchpad, there might be enough real estate to do descriptions as it is now, especially if they do them in different columns - a web column, an apps column, a quick actions column. They seem to be into columns on the touchpad, anyway.
