If you have an alias app so that you can create a stack on the dock, launchpad (for some reason) treats it as an individual app. So now I have 2 of many different apps that are part of a suite. For example, MS Office and iWork. I deleted the iWork aliases as a test and they are now gone from Launchpad but I no longer can have that stack on my dock. Anyone else figure out a workaround so you don't have to have dupes of apps in launchpad?
