Highlighting invalid objects is a nice feature, but it would also be nice to "find" invalid objects in a script.
Running SQL Format on a script with an invalid object in it runs fine and gives no error, it just doesn't prefix the object (like a table) with the schema.
It would be nice to have a quick and easy way to "go to next invalid object" or even for when you run SQL Format to have it bring up a warning saying "this/these object/s appear to be invalid".
