Shannon asked: I just don’t understand all the technical jargon when I search for info and I hear this is a must have app but I don’t get what it does other than you can hide icons. Is it user friendly for someone like myself who is basically computer illiterate?

bossprefs is more of a modification application than being a user-friendly straight to the point app. So I suggest that you avoid it.
Speaking of it’s abilities. It helps you rename, remove, hide and organize your icons. Also, altering some internal preferences.
