Code review comment for lp://qastaging/~dyams/unity-2d/launcher-DnD

Functionally looks fine, except for the fact that launcher doesn't slide out in IntelliHide when you reach the edge when dragging, could you please investigate whether that's doable easily? That might require design input later (should the launcher show as soon as something is being dragged? maybe just the apps that support the mimetype should slide out?).
