One more thing is that in the latest test version 1.2108 you can also redirect that message to the console, you just have to enable the console plugin and then you can quickly read the error message on the console plugin screen. Then you do not have to open the error file again and again.
And you can also Console.Writeline to the console from macros and plugins which is a handy feature for macros and plugins developments.
The console plugin just catches the stdout (standard output) of the application, so everything you write onto the stdout in the app you can read on the console plugin window.
