There are two dock options: - minimising to the dock with the app appearing on the right-side near the trash can, - minimising to the dock and back into the app itself. What are the pros and cons of the two options? Currently, I have it set so that the minimised app goes back into the app (so that the dock doesn't grow longer). However, the close and minimise button (at the top left of the app) end up with the same behaviour. Or am I wrong? What is the point of the minimised app appearing next to the trash can?
