I hate Visual Studio. It takes 2 minutes to load- it is a glorified word processor- sure it has compilers but that's the backend work shouldn't be doing any of that at the start. It should take 10 seconds to load. It has absurd number of annoying checkers like unused attributes or function not initialized (constantly hits on Start ()in monobehavior) I even told to skip that nonsense and it still does it. It doesn't however check like infinite loops easily accidentally do. You can't duplicate a script because it can't do the simple thing of ensuring file name and class match.
