[Unreleased]

First public release.

Roadster X, an add-on car (roadsterx) for GTA IV: The Complete Edition 1.2.0.59. No stock car is replaced.
Two-seat cabin with butterfly doors: the driver and one passenger.
Jump: tap to hop over traffic; hold to keep rising, so the hold sets the height, then let go to drop onto the soft landing.
Hover and fly on ten cold-gas thrusters: double-tap to hover, then climb (jump button, accelerator, or look up to climb straight up), descend, travel and boost. Double-tap again to drop; the thrusters catch the car just above the ground. In the air, one press of the jump button fires the jets again.
Air tricks (flips, rolls, spins), kickflips on the road, and quick 180 and 360 spins.
Soft landings for jumps, ramp jumps and ledge drops.
Turn smoothly on the spot from a standstill (push further to turn faster), and powered drifts when moving.
Active rear wing (Auto, Downforce, Airbrake, Stowed) and speed-scaled downforce with fan suction.
Water rescue: the thrusters lift the car back out of water (can be turned off).
On-screen systems panel with gauges and the controls that matter right now.
Original synthesized sounds: thrusters, wing servo, doors and motor.
Every setting in plugins/RoadsterX.ini, reloadable while you play.

One passenger only (it's a two-seater), and companions can take a moment at the butterfly doors.
Developed and tested on a Mac with CrossOver. Windows should behave the same; please report anything that doesn't.
