Ubuntu :: Dynamic Multi Display Management?

i would like to know if there is anything like this out there or in development and if not i think there should be. i feel that one of the areas that ubuntu still lacks majorly is when it comes to handling multi display.most people these days are using notebooks and are moving around a lot, and if your like me working as a software dev you need to be able to work from home running a different external display next to your internal, then when you get to work you need to maybe run two external displays or maybe a totally different display next to your internal, sometimes you'll need to connect to a projector in a meeting and do a demo.

At the moment, there is no easy way to do this unless you have a half an hour everytime to configure your displays manually,which goes without saying that its not quite what anybody is looking for.i'm looking for something that works similar to OSX's display manager.where you plug in a screen and poof, its there. and then mayb you can configure what your system should do when that specific monitor is plugged in and it will remember that configuration. so for instance you have a internal 15" with a res of 1440x960 then you want to plug in your 1080p 24", so boom it picks it up but its not configured yet.so it jus mirrors by default, then you decide ok, when this screen is pluggd in, i want it to extend my desktop onto it, and make it the primary monitor. ok cool so its set,so now when you plug it out, your system detects that your display setup has changed, then does a recheck of your active displays, and sets up the appropriate configuration, in this case only the internal is available so it will just go back to the internal, setting it back as the primary and moving all the windows that was on the external back to the internal.i think this would be a invaluable feature for a mobile professional.
