Visualize spaces in mission control

Hello, i love that possibility of having multiple desktops to organize my work. That function can be the first i'd name if you'd ask me "why don't you come back to Windows?". I use it all day from the first introduction, having 5 desktops with different tasks arranged, plus Calendar and Mail always open in screen view. I taught friends to use it, and they where astonished.

BUT: i loved the first version, when you opened mission control and it showed all the spaces, so i could see it all at first glance, and i hated when Apple introduced that new version that hides the spaces, and you have to go on the area with the pointer to fully visualize the content of the spaces. Nothing to die for, but i surely would reactivate the good old "show all" mode if i could. I searched in the settings but without success.

Thank You in advance
