Applications in ~/Applications not shown in Applications folder in dock I just noticed that brew cask install symlinks to ~/Applications. This works fine, but the application item in my dock does not show apps from that folder. Is it supposed to work this way? I expected to have an aggregated view of /Applications and ~/Applications in my dock.
Each item in the dock is a single folder. 

OS X does not have merged folder views except in Finder where there are Smart folders

However you could create a smart folder in Finder of Kind is Application and drag that to the Dock
