Manage the exception database (add your own entries)

This tool ships with a built-in set of common .NET exceptions (see the BUILT_IN_EXCEPTIONS object at the top of the script in this file). You can also add project-specific or custom exceptions here at runtime — they're saved in this browser's local storage and merged with the built-in database automatically.
