The icon in Launchpad look huge on my iMac and I usually like my icons fairly small.
Is there a setting to resize the icon app size in Lauchpad?
I have found no way to do that, nor have I heard of a way. MacOSXHints is the place to watch for this kind of thing.
I have created folders in effect by dropping similar apps onto each other. All QuickTime apps are together. All Maintenance Apps are together, as are media viewing apps, etc. I also move the least used apps to page 2
This reduces the number of pages for Launchpad and makes apps more accessible for me. My most-used apps are still in my Dock so LP is rarely invoked.
This doesn't give you the solution you wanted, but may help as workaround.
