I just thought of this while in a meeting, haven’t done any research on if it’s possible or not today. I think it’d be nice to have the ‘Report Error’ link setup to report errors in a user-defined way, such as sending the error to a specific e-mail account, logging the error to a specific table, writing the error to an RSS feed, etc.
Gateway config page -> Configuration Heading -> Gateway settings -> Bottom section titled Error Reporting
That covers e-mail at least. The other options are pretty cool addon ideas.
