Disable auto-unminimize when switching back to an app

Hi,

When you switch back to an app with all of its windows minimized, the most recent one gets automatically unminimized.

This only works when switching back to an app by clicking on its dock icon or via spotlight activation. Cmd-tab switching does not unminimize any window.

This is a pretty annoying issue when, for example: You are at your workplace, switch back to Safari to look something up on Google and have your 27-inch Thunderbolt Display filled with your last evening's web page about your recent role playing game acquisition. Of course, this happens just when your boss comes to see you (Even if you loose the next half-hour listening to him about how he slayed a dragon while being chased by mammoths*).

So, I am looking for a way to disable this behavior.

Maybe there is some hidden prefs that can be changed from command line? But I am not sure if this is a system-wide or app behavior. It might as well suits me to just disable it for Safari only. Altough I see no usability gain to have windows being automatically unminimized when switching back to apps.

Any idea welcome!
