On Android, one does not want )OFF to actually kill the process itself, since this instantly kills everything, which is problematic for an Android application.
Of course, I can check the command typed in the input field before sending it to the interpreter, but with the arrival of commands being executable, this is not a complete solution. Would it make sense to add a callback that I can set that will be called when the )OFF command is issued, and you only fall back to the default behaviour if this callback is NULL? Regards, Elias
