The Improved Maneuverability feat boosts your maneuverability by one step. If you're average or above, you can now hover, which beats the Hover feat by a mile (unless you're large enough to cause tornadic winds).
You might also want to look at Flyby Attack. It's like Ride-by Attack, Shot on the Run, Spring Attack, AND that feat that allows you to cast spells in the middle of a move action, all in one.
