Being able to see a tally of the number of actions added in the action tab would make comparing similar (clone) Tasks that are suppose to have identical Run task X that has the same purpose but different restrictions or whatever.
Sometimes when you copy a master task, those cloned tasks might later have add new actions manually added to them all but you may miss one. The tally will tell likely point this out.
This is similar concept when copying files in Windows Explorer and using the file count as your comparison gauge between both folders.
This idea might be useful for the restriction tab as well in a task and Location Properties where you can see all Object contents.
