If you decide that you actually want something to do with Launchpad. Then I have some tips to help you tame it. I have thrown my hands up. It's useless for me. You can't remove things from Launchpad with ctr+opt+cmd. This great feature was killed after Lion DP3. The best thing to do is to completely empty launchpad then drag apps into it from scratch. Remember that all new apps purchased from the Mac App store will automatically go there.
Here's the cure. Open terminal cmd+spacebar type in terminal and hit return. When it launches copy this code directly from the post and past it right into the terminal window:
sqlite3 ~/Library/Application\ Support/Dock/*.db 'DELETE FROM apps;' && killall Dock
Hit return and close terminal. When you open launchpad again it should be empty. If there is a stray empty folder simply drag an app of any kind into launchpad. Open launch pad. Move the app icon into the empty folder, open the folder, then drag the icon back into the launchpad backdrop and the folder will go away on it's own.
Now you can add just the apps that you want, and arrange them as you want to also.
Is there a way to go back to get your Launchpad apps back? I grid it your way but now want to go back and get them back. Any idea how to do this?
