Looking good. The flyout vs accordion wars seems never-ending.
I won't complain, but still prefer the accordion style, it's more visible, memorable, requires less dexterity from novice users, and adapts better to input methods other than a mouse.
It shouldn't. The optimization is just responsive design for the admin area. Twenty Eleven[1], the default theme, has a responsive design as well. I don't see either of those things taking away from a business like Onswipe. Until more responsive design themes get into the WP repository, that is.
Since I didn't spot the link right away.
