In the example we use the property opacity. I asked myself how to get a quick overview on all possible
properties (methods) of a class and its subclasses (here NSView). Ok, I could look up any class/subclass in the
the documentation but this would be a burdensome way to do it. I am pretty sure that there is an easier way to solve this.
Maybe someone can help me in this issue. btw. I tried out AppKiDo, but it seems, that it can not really help me with that problem.
