Ok, but having to go to the edge of the screen or use a modifier key makes it more painful than it should be. Before when Dashboard was just like an extra desktop to the left of your other desktops, you could just three-finger swipe from anywhere on the screen, any time. Same gesture as switching between desktops. It works that way on iOS too. So simple!

I understand why they dropped the original Dashboard, its widget platform was a technological dead-end. But now that widgets are back it would be awesome if they made the new widgets work like the old Dashboard again.
