Sorry, my problem with reveal error was user error - I hadn't realized you can't do anything with the error until you press the control key, also I may have confused the line 'error' which is ctrl clickable with the line 'note' which is not.
Another issue I have is the library for IRRemote 3.9.0 - the IDE suggests I install 3.9 every time I start it up. If I press install it says 3.9 already installed. Maybe the fact that this library has a hpp file confuses it?
