Well, my first OXP is a small one - just three functional lines!
The "keyboard Cobra" add-on, when installed, applies a damper to the pitch, roll and yaw of the standard Oolite Cobra Mark III, reducing each to 40% to 50% of their original values, thereby making it easier to line up the ship with targets.

At the time of writing, only the standard Cobbie 3 is affected.
Version 1.1: All core Oolite ships are affected, but no OXP ships yet (other than the Shady Sugs Cobbie Mk 3 because that's what I fly.)
: The Far Star Murderer and the Dragon ships are also included.
Mouse and joystick players who install this OXP will be equally slowed down.
While the Cobra Mark III is a great ship to fly, those species without opposable thumbs, extensible claw-mandibles, pseudopodia or other means of gripping the analogue mouse / joystick astrogational navigation equipment struggle with the alternative keyboard-only flight interface, primarily because the digital turn/no turn does not work well with the Cobbie's super performance.
To aid these customers - and any space-travelling cold-blooded, sloth-like or plant-based life forms - the ship control can be converted to turn more slowly. This is achieved by applying this OXP, which converts the Cobra Mk III into a Cobra Mk III-KB. Resale value is in no way affected and there is no cost involved.
There is no need for everyone to know you are using the backup keyboard controls so only you know it is a Mark III-KB. This means you will never see a Mk III-KB in the spacelanes. Ships for sale which can take the keyboard adaptation will have "-KB" or "(KB)" at the end of their name. But should you need a new Cobra Mark III, such as when you use your Escape Capsule, rest assured the dockyard will discretely fit your required keyboard adaptation to your new Cobra Mk III at no cost to you.
