Shihab Mehboob (@JPEGuin) shared a useful tip on Twitter, where you can expand the amount of rows and columns in Launchpad.

Turns out you can do this by altering the following values via Terminal:

defaults write com.apple.dock springboard-rows -int 8 defaults write com.apple.dock springboard-columns -int 8

For these changes to have effect, you’ll need to restart the Dock. You can do this via Activity Monitor or by typing killall Dock .

Here’s what mine looks like on my 16″ MBP:

So much better than the massive icons that come by default.
