A lot of people have macbooks and external secondary displays. Just as you said, these people should be able to go fullscreen on their laptop and still utilize the connected display...
Yes, of course. I didn’t say the feature shouldn’t be there, I said that multi-monitor was broken only for fullscreen, so “Mavericks adds multi-monitor support” is a slight overstatement.
But yeah, I see people have strong feelings about this issue, I just personally don’t get it.
