The buggy behavior can definitely occur for those that don't appropriately follow a RESTful interface. With regards to displaying messaging, this is something I'm very much looking to add to both modes. In regards to templating the initial thought was some HTML that the user could include or would be default that would float as an overlay on a page to indicate the mode. Though I'm mostly curious as to what users would most want to see here before implementing something that people may not want. As for the environment variables, I may be biased but being at Heroku we very much enjoy this approach. It reduces risk of having config included with code which can be hard to debug at times.
