I've hook up my rMBP to a 30inch Apple Display and it drives me NUTS the way my full screen windows never stay in the same place. Quite simply I want to be able to instantly toggle a work environment. JUST like you do on Photoshop. This would put my calendar at full screen on the furthermost space of my rMBP, the next one would be Mail etc etc At the moment every time I disconnect and then reconnect I have to re-sort these windows. Sometimes, I don't want mail fullscreen so I drag that I'd like to be able to instantly toggle it back the way it was. If calendar is quit then relaunch it, if mail is full screen but in the 30inch space then move it. I've tried the following apps: Stay Breeze Display Maid None of them seem to work properly. They can't really deal with multiple spaces and full-screen apps. I've tried keyboard maestro but either it doesn't do what I want or I can't work out how to make it do what I want. Any help or advice here would be very much appreciated. I can't believe no one has come up with a solution yet! Does no one else want this? Didn't you used to be able to state apps to open in certain windows? Not full screen and not what space but nevertheless.
