I'm the author of Exodus (no affiliation with the recent itunes app gay-cure scandal), and I wanted to put a plea out there that if any of you do try this out and encounter any issues with it, please feel free to post issues on github. It is a simple app, and I don't really intend to do significantly more work on it, but I would like to fix any bugs that arise.
Rendering of exceptions is enabled by default in development, but if you're running the app in "production" (which is the default environment), just enable the debug > renderExceptions flag inside config/settings/production.php.
Thanks!
