just some little things. There's another OSD item ("rotation bars") which shows the relative rotation velocity,, mostly to be an aid for players who struggle with killing a tumble.  There's a "directionalizer" mesh on the drone,, it can be toggled on and then there's a transparent collider-less triangle pointing to the front. (mostly for use with exterior camera flying) ,,, maybe some fiddling with the lighting. I'm far from having any idea how to go about the lighting. 

edit:: additionally ,, I've updated the rotation stabilization so that while connected to a weight, it will use both rotational thrust and horizontal/vertical thrust to stabilize rotation. This is because while docked to a weight, rotational thrust alone is less capable, and with the heavier weights almost completely benign. At first I thought it would just be the nature of dockable weights that rotation stabilization would be largely ineffective, but at present it is working pretty well with the addition of translation thrust while connected to weights. It may feel slow sometimes when compared to unconnected, but in part that's just my stabilization loop, which I hope to adjust in the future to be something that resembles tuneable PID controllers such as what is on hobby quadcopters. For now the best way to increase the stabilization performance is to increase the vehicle torque while connected to a weight, which is easy enough by toggling "double rotation". (although, personally I like the idea that the player must deal with the limitations of lugging weight around,, however depending on the desired style of play, higher performance rotation while docked to a weight may be desired).
