So I'm running a bunch of Full Screen Apps in Snow Leopard... mostly games but others as well. They behave just like any other application/window. The menu bar dutifully "hides" unless I move a mouse arrow to the top of the screen - just like FS apps in Lion/Mountain Lion. When I use Snow Leopard's Expose however, these FS windows mingle happily with all the other windows I have in that Space (desktop) be they Full Screen or not. Plus, with dual monitors, I can have a full screen window in each one. My question is... Why did Apple suddenly decree that full screen windows will henceforth be so special they can no longer slum around on the same desktop as those windows that aren't running in full screen? What am I missing? In Snow Leopard, I group my "windows" and apps by job, category, whatever... and coral them in their own unique desktop (space). It's how I 'think'. It's how I organize my work. I believe this is how "most" people organize things. This is one of my major annoyances with Lion/ML and why I'm still on Snow Leopard. Like I said... I'm missing something.
