The reason I ask this is if you have a problem with the site and it takes you awhile to fix the issues in debug mode. Members can see the debug messages. However, I know you can turn on maintenance mode this kills all traffic though.
I was just wondering if there was a way for debug mode to only show for admins and if not I think it would be a great update for Oxwall to help keep the site active but show errors to the admin so he/she can work on them while members enjoy the website.
