Hi!
Regarding the interior brightness, I would recommend checking your monitor's gamma setting, our graphics are tuned on calibrated monitors, appearances can be different on different monitors. You can also try turning on the cabin light, which should brighten stuff up a bit as well.
Regarding SVS, I have forwarded this on to the SVS developer, not quite sure what is going on there, something seems up with the mesh parsing possibly.
Regarding tail wheel handling. We are constrained by LR on the ground handling characteristics. There isn't an X-Plane setting to put the plane in an easy mode. Keeping the engine in Beta and being on top of the toe brakes is the most important thing for handling - the plane is a beast! We also include the retract tricycle variant for this reason, which has much easier ground handling.
