On Snow Leopard I used to have 9 spaces organised just for my needs. Unfortunately new Mission Control approach broke it completely and I'm still feeling a bit lost with the new horizontal approach.
Anyway, it seemed that the the settings for number of spaces and apps assignments have been kept after the upgrade. I'd like to reset this to the default state. Reducing number of spaces is quite trivial, but what about app assignments?
Is the preferences pane for this long gone now?
