300/600 a few questions

[cloudfreak1]

i like the Plane very much but i have a few questions: 
Nav Selector  in VOR-mode and ND on ROSE there is no working To/From indicator ,is this in real the same? 
There are also no 45° markings!
ND in ARC-mode is not working it shows  in the opposite direction with full deflection. is this a bug?
which commands are working for the ENG1 and 2 Fuel On/OFF switches?
which command are working for the screw left of A/THR?
a small bug: Landing lights are retracting  already if switching from ON to OFF
