I don’t like application installers to add icons to my dock without my permission. I prefer to choose what appears in the dock. When I installed Stuffit Deluxe 11 it added icons for each of its applications to my dock & I didn’t notice any option to say whether or not I wanted those icons added. It also has a very sneaky installer. You simply drag it to your application folder and when you run it the first time it launches a setup assistant that looks a lot like Apple’s installer.
