If you decide you don't want to renew subs for a bit be sure to archive the apps before it ends otherwise you won't have anything to restore,impulse only shows the latest it doesn't list your subs cut off point or any apps you were entitled to before subs end,that also means you need to use a method to store them externally from the comp in case of failure,it will save a hassle of starting a support ticket to retrieve stuff...
