Development mode for personal IP address

the lateral thinking mode is this : you have your web set up on local host . thats where you play with it , fix bugs and improve it. on that one you have development mode. your live web is a clone of your dev web on local host, and in that case its set to production mode. Every improvement you do on localhost you push to live. No need then to change modeon live
