The easiest way to make sure not to miss any errors or warnings in any code file.
See the change log for changes and road map.
Sometimes it can be hard to tell if the file you're editing contains errors. Perhaps the error is all the way to the bottom of the file and you don't notice it. You might save the file containing the error and something bad happens when you then try to run your application.
You can decide if you wish to show errors, warnings and/or messages. Just right-click on the icons to enter edit mode. Then check the checkboxes for each of the error types you wish to see.
